Why don’t they tell you the downside of Ventilator’s? This is pissing me off. They should explain that a person should only be on a Ventilator for 3-7 days. ANYTHING longer it causes LIFE LONG problems and Disease’s. I was on a Ventilator for 2+ weeks and now have Restrictive Airway Disease at 32% intake of oxygen and Obstructive Pulmonary Disease at 52% out take. Also Severe Asthma all caused by my Ventilator. This is NOT LIVING!
Wow
I was wondering… Do they have a temperature control setting? What if you could heat up the air going in high enough to kill the virus? Would it still be safe for the lungs? Not exactly sure but what I’ve read it seems like 39 degrees C? I apologize in advance if this is a stupid question…
Rona brought us here
Hole in throat machine breaths for you ?
No hole in the throat ?
Are the iron lungs of the 1950s of any use?
How does a ventilator help you if you have pneumonia-like symptoms and the alveolae are filled with fluid? How can gas exchange take place?
bomaite1 watch his ARDS in regard to coronavirus. He answers you’re question.
Ventilators will work for awhile but once the coronavirus spreads into your lungs Ventilators are useless, the coronavirus will start to control your breathing like a spider web and once that spider web stops the contraction of your breathing your already dead.
Yep , here in case it comes to an old Gyn to set the vents : Lordy , lordy
I am here becoz of covid 19. Thank you doctor , immensely for the valuable video.
Is it air or oxygen?
Sir, I am not a medical professional…but with coronavirus disaster going on…i got curious. Question: do we have to go via lungs. Can we not divert blood out of some major veins like abdominal vena cava, that carry larger volumes, analyze o2, co2 levels, and based on result, add oxygen ( i don’t know if we can just mix o2 in blood) and then reroute to the vein? Let lung do what it is doing..and blood pressure is maintained by heart anyway. This will bypass the compliance code etc. I don’t even know if this makes sense..
Actually I want to see where the air goes from ventilators, does it being filtered?
Great explanation dr. Thanks
An inventor wondering about CoVid-19 ventilator shortage emergency situations; and wonder whether in patient controlled breathing; if the patient is conscious, Can the patient use a simple tube held in the mouth to inhale and if the patient is prone does tilting the patient help them with regards to fluids in the lungs? Also will diuretics help the patient get rid of some of that lung fluid? If you had to program pressure control only, what PSI might be shared by several patients on the same tank of compressed air?
From what I understand.. Ventilators themselves are quite easy to build, it’s the operation of said ventilator that is complicated, there has been mechanical hand powered ventilators since the early 1900s. An engineering student made a 3d printable open source ventilator that can be easily mass produced. The issue is creating code and a device that can figure out a patient’s correct natural breath cadence and then being able to tell the ventilator to match it and maintain it.. and then of course a monitor to display said data.. What I don’t get is why they aren’t mass producing hand powered ventilators like that 3d printable one.. that way at minimum instead of someone going on ZERO ventilators and dying, they can at least hand pump them or use some servos and basic coding to make it pump in and out at the average pace.
. I could make one of those in my garage in 24 hours.
First off let me thank all the RN’s Doctors and medical professionals for doing what they do. I’m sure as patients it’s just as scary for you because you have families to go home to even without coronavirus everyday you risk catching something that can end your life. If you’re reading this and thank you. You have come so far in your achievements and I know damn well for sure more needs to be done to protect doctors nurses and staff all medical professionals from dying and bringing this home to their families. And worst of all leaving their families behind. Listen all these doctors nurses and medical professionals didn’t sacrifice cold pizza and ramen noodle cram sessions to have it end over this. I know this is a YouTube comments section but you are medical providers advocate for us but in times like this where no doctor ask for anything in return when a patient walks out that room (AND NO ONE SAY MONEY) we need to protect our medical soldiers out in the front lines. Without doctors, without ER physician’s, no matter what your profession is Neurologist, we need you healthy and not have fear of not making it home to your families I strongly advocate for better protections for medical professionals. When they are comfortable they will make us comfortable. And of course they want us to be pain free and comfortable but it will eases their anxiety and they won’t be dropping like flies. It’s a nightmare for hell so please let’s stand together and if we can find a way to raise more supplies for nurses in NY CT NJ I’m down. Nurses and Doctors are always there for us 24/7 365 but they will never tell us they really need us. ONLY TO BE HOME but we can do something thank you guys all again I admire you ALL
this is really well explained
Is this truly the best Choice for covid19?
Good info to learn… Thank you….
The concepts are explained so beautifully and in such simple terms! It takes a genius to explain such complex things to a layman so Medcram guys – you are geniuses! Else any medical technician/doctor can pepper the entire talk with jargon and screw up one’s interest in learning the concepts.
A GREAT INSTRUCTIONAL MEDICAL FORUM WITH UPDATES AND TECHNICAL ASSISTANCE FOR ALL!
I learned quite a bit. I was always curious what sealed the tube in your throat. The problem is getting oxygen in, and drawing CO2 out. I’m still curious about tilting the body, the way before iron lung.
progressive care RN training for critical care d/t CoVid 19
Same!!
thanks very much!!!!!
High quality instruction 🙂
You know why you’re here.
Temperature controller AND Rh. Air intake pressure.
NOT EXPLAINED ABOUT VENTILATOR SPECIFICATION FILTERATION LEVEL . LEVEL OF MICRON AIR PURIFICATION . KILLING INTAKE AIR AND GERM KILLING BY ELECTRONIC FILTER. Before out side air into ventilator.
Can’t build your own ventilator. Beside you need a well trained person who know what he’s doing like a respiratory therapist or respiratory therapist technician. This is a specialized field with its own degree and certification that takes years of studies to get
There have been times, when all that was available, was a person squeezing a bag. It could come to that again, or doctors will decide who has best chance, and who will not be treated.
In what circumstances do you ventilate a person with potentially compliant lungs? In covid19, for instance, the lungs will not take in air, so how is a respirator working?
I’m here to prep for my last nursing exam (for advanced med surg)
yes
Excellent device. Calmly explained. Mohan Devale. +91 9223257444
Oddly everyone is demanding testing but none asked for how the treatment was for Covid19.
Now we look at ventilator, but why? What is it for? Is it good for Covid19 patients? If you don’t know the treatment, why asking for a ventilator?
You said, yes, I how how they treat patients in the hospital. You are good, but how about the public?
very nicely explained
Could a cpap machine be converted to a ventilator ? Could a cpap machine help a person who is having trouble breathing ?
Sounds lik a clap machine. How is it different?
Well done. Appreciate it. Thank U.
Thank you!
Yep. Here for Corona. I’m a neurologist. Haven’t dealt with ventilator settings in over 2 decades.
I’m a retired radiographer who mostly worked in MRI. I have a new level of respect for Respiratory Techs.
Damn as a psychiatrist it hits me in the feels.
love the no nonsense terminology – as someone once said – the more you know about a subject the simpler you can make it sound
Sooooo accurate!!!
Golden words-The more you know about the subject, the simpler you can make it sound.
Who’s here to learn how to start building your own?
Gotta learn now. Great minds think alike. Stay safe my friend.
Sounds like a little hell on earth
AC might be called Pt Initiated. Compliance is the inverse, or complement, of inflation Resistance(ie due to fibrosis, obesity, or fluid collection). The various alarms(vol, rate, pressure, pCO2-out, pO2-out, etc.) should always be set, & tailored for near normal respiration, in case the patient’s respiratory performance changes for the worse.
I’m seeing this because of Wuhan Coronavirus
This is great. Since you’re talking about tracheostomy, the ventilator should go to the stick-figure’s neck, not their mouth. The mouth is confusing for students
I noticed the new Dyson V12 animal has a digital display, maybe the rug cleaning mode covers all this !
Thank you!
i am just bored
Question can a cpap or bipap machine be repurposed / reprogramed by manufacturers to work as an instant mechanical ventilator?
Complete please
What do these machines give to the pacients? Pure air, pure oxigen, or a mixture of both? If the last, in what proportions?
Hi doctor, my country Indonesia has shortage of hospital beds for COVID-19 like anywhere in the world. Do you think I should stock up oxygen tank for home treatment? At least that is the best thing one can do? Do you have materials on how to operate oxygen tank at home?
I was wondering on how the exhaust gases are scrubbed
there is another passage in the tube, where the input valve close and the output valve opens, passing the exhaust into a pressure transducer that make the beep sound to make sure that everything is going okay.
These are just brilliant. Excellent teacher, great level of detail. Thanks!
many thanks Doctor.
This is fascinating. I’m not in medicine – I’m a software engineer – but this makes perfect sense! Off the wall question: are there ‘industry standards’ for interchangeable ventilator parts?
i am beginning to think that kids should be taught health science as a prerequisite in all schools from an early age, starting from the simple basics (hygiene and the rudiments of biology) to an elective skill in the health field, from which they may proceed as desired in collage. in this way, there is a ready reserve of competence. this is true of many other professions. we really need to teach young ones as early as poss, and provide useful skills that give dependable employment and benefit to everyone. and when high school is over, they can elect whatever line/career/craft/aprenticeship they may wish to pursue.
Nice review! Just what I needed after not having written vent orders for 20 years. It’s all still in my brain just a bit rusty. God forbid my ICU skills need to be used again. Makes me nervous just thinking about it, not the virus!
What certificate do you need to fix this equipment?
Roland Reebs said: Well done! And yes, my interest in ventilators came about because of covid-19.
The Italian priest who died because he gave to others his ventilator 😭 brought me here, who else?
March 25, 2020 🙏🏼 God bless world!
how mind boggling is it that 50 priests have died from it too . giving last rites i guess ?
Skype id plz
Thanks for the lecture. very detailed explained.💖
I built one for myself and tested it but it took all the air out of my lungs and I almost died. I must have got the wires mixed.
In post #35 you spoke of Quercetin and it’s benefit in managing Ebola and Sars. Even though the dosage of Quercetin is so variable, it still seems to be a way of providing prevention and possible treatment. This information is very significant and so much so, I have started taking 500mg four times a day along with 20mg of zinc. I am interested to know why you have not professed the widespread use of it?
cmv =contol manual ventilation . the ventilator breath will be given regardless of trigger.
can medical ozone therapy have a good effect ? Any reliable studies ?
Clear and simple introduction to mechanical ventilator dynamics. Well done.
I love smart people <3
Surely a CPAP home machine can be used in certain instances when a hospital-grade ventilator is not needed. Nasa engineers can design a a dapter for a CPAP to endotracheal tube ETT. They did save the Appolo 13 astronauts with a makeshift filter put together from duct tape and a few other materials in the lunar module in the early seventies.
CPAP machine doesn’t have ventilator settings on it. Someone on a home CPAP machine is able to breathe on their own. An intubated patient may or may not initiate breaths themselves.
Dyson have designed their own ventilator for the UK and they are being made.
I came for the free pizza… but I stayed for the ventilation. 💨
3:19
Dr, Segeult thank you for all your videos. I am a nurse educator currently working with covid19 patients. You are an unbelievable presenter and educator.
thanks.
Video not real clear
What exactly does it mean for a lung to be “compliant”? Obviously, this is not the layman’s use of the term. And how exactly does the machine know whether or not the patient is trying to breath on their own? Does a pressure sensor in the tube detect a “suck” or a “blow” or does an accelerometer detect a rising / falling chest movement, or…… what?
I’m a mechanical engineer and I love your videos. They are very interesting and informative. Thanks!
The high resolution graphics are reassuring.
Why is the patient standing up? Is s/he hung from the ceiling or is it their responsibility? And how do the bells work and when blow a whistle, is it sterile?
I am watching this as i have decided to build a cheap and mobile mechanical ventilator myself as a mechanical engineer to battle corona virus. Kindly share your inputs
Can the ventilators that are used for sleep apnea be modified to work for corona virus patients? I’ll bet there’s a lot of them out there that people don’t use that are basically brand-new.
An Ontario🇨🇦Canada🇨🇦 Doc has figured out a way to DOUBLE ventilator capacity!
There’s a catch……the patients need to be of similar size and lung capacity.
It’s still fantastic and if one vent can help two people, less horribly difficult decisions will have to be made by Docs like what has/is taking place in Italy……who gets a ventilator?
Small miracle but still a miracle and heck yeah, any miracle right now is welcome! Way to go Dr. Gauthier!!!
I am an RN who may be called back to the hospital to care for patients…awesome to be able refresh on this while waiting for the call… it has been a lot of years since ICU for me. Thank you
@CyclePat
No cpap would not work or be sufficient for ventilation because CPAP deals mostly with oxygenation issues not ventilation. Covid-19 pt usually develop ARDS so it would be hard to use cpap. The pressure from the CPAP machine is not the same as a pressure from the ventilators.
An advanced BIPAP with backup rate, APRV or SIMV-volume regulated -pressure control on the ventilator would be better options. You cannot have oxygenation without ventilation.
@CyclePat good question
In Australia, we don’t have a lot of respiratory therapists. Critical Care trained nurses are very capable in looking after ventilated patients 🙂
Just asking… would a CPAP Machine be sufficient ventilation (possibly) duirng this outbreak/pandemic?
Respiratory Therapist Run Ventilators Period. especially in critical care patients.. if you want to start to kill patients a painful death by all means take a 10 minuet video tutorial and have at it … we have only gone to school for 2-4 years to learn about hemodynamics.. i not deminishing the job of our RN we love and need them.. but we need to stay in our own lane. or we will see masive crashes..
I was told by a Doctor and many ICU nurses that putting a patient on a ventilator was fraught with many dangers especially for the elderly patient. Not that the equipment would fail to sustain homeostasis, but while ventilated it provides many a patient with a path way for a pseudomonas infection which usually requires both a gram positive antimicrobial and a gram negative antimicrobial, e.g. Imipenem and Amikacin given together in the right amounts. However, if they survive that; I was told the biggest hurdle was successfully getting them off the ventilator to sustain breathing on their own once off of the machine. I can recall where a family had to make the decision whether or not to ventilate their elderly Grandmother. Their Doctor who was also my Mother’s Doctor was recommending that they don’t do it and take their chances for the survival of their Grandmother without its use. However, they chose to ventilate her. At first after she got off the ventilator she appeared to be in good health and it looked as though she was going to make it. But without any warnings she took a sudden turn for the worse had very labored breathing and died. This happened about 36 hours after she had been taken off the ventilator. The family was stunned and was in shock. However, their Doctor reminded them he warned them not to ventilate her due to what he predicted could have a high percentage of occuring.
So my question is why is the mortality rate so high for the elderly; subsequent to being removed from a ventilator?
Pulmonary flashback
I have a vocal cord paralysis (left vocal cord always in closed position). This was caused when my left recurrent laryngeal nerve was damaged during a partial thyroidectomy and I have since had the left vocal cord bulked up. Should I ever need to be intubated, could that still be done with one closed vocal cord? Can one be on a ventilator without the ETT going past the vocal cords? This terrifies me.
How Gtech are going to sort all these complex features in just a few days churning out 1000 ventilators a day must be a mammoth task, I wish them every bit of luck and we need it desperately, I think they haven’t seen this video, may be they should , no disrespect, they are trying to help, but it appears their ventilator must be very simple and not so complex operations , I heard their machines don’t require electricity, it is propelled by the oxygen pressure, which can be regulated in a similar way as is done by gas regulators, which does not require any electricity, my guess is it is working on the principle of vacuum servo assistance, as used in car multiplying braking force in cars, where a small pressure controls a valve and uses the atmospheric pressure to generates higher force, so it can be arranged where when a patient tries to inhale oxygen, it creates a negative pressure which controls a valve that lets in oxygen under certain pressure, when the lungs are fully inflated, the valve closes and pressure builds up as the patient also tries to force out the air, this lets open another valve which allows the air from the lungs escapes by patients own lungs relaxing, both inlet and outlet valve in conjunction with incoming oxygen pressure needs to be balanced intricately to achieve perfect breathing, yes it can be done, without due complexity and requiring any electronics, however it will only work on patients who have some breathing capacity, if a patient lungs have collapsed and cannot breath at all then this device would not work, it is a form of assistance breathing, where the weak lungs are assisted by servo mechanism and oxygen pressure. It cannot work on patients who have zero breathing and require forced breathing, you would then require proper spec machine to do that.
I’m here to see what’s in my near future. I’m high risk. Good health everyone.
@Kitty C yes!
Tony Cotto GOD bless you!!🙏🏽
@Kitty C Unfortunately some people have to lower there immune system to stop transplant organ rejection and other reasons.
Tony Cotto build up your immune system , doctors are saying daily vitamin D3 is essential
4:37 I am no doctor but i think the output is not just CO2. It is a mixture CO2, unabsorbed O2, water vapour and China Virus. Am I right or am i right? I had great SAT2 grades.
Depends on the circuit and the filters used.
Could be useful with this Covid-19 monster.
I sure as hell hope that nobody has any idea of watching a video and think they can manage a Covid patient with ARDS on mechanical ventilation??! You best leave that to a well trained and experienced Respiratory Therapist (RRT). They are the best trained didactically and clinically to initiate and manage advanced modes of mechanical ventilation.
Nah, people are smarter than that. They just think this is safer than banging strangers on the beach.
Great intro!
They never knew how popular this video would become
I take 12 breaths per minute….
Is ventilation used in Italy Hospitals for Coronavirus treatment?
Of course. But possibly not for all, since there are to few ventilators.
Me I’m getting to know my new friend
RIP
Gallows humor
Your new friend – the ventilator? 😨
Should I be freaked out this popped up on my feed?
No, you shouldn’t. Due to the attention CoViD19 is getting, YouTube is suggesting videos with some connection to CoViD19 far more frequently. It may have exceeded the threshold where you will be suggested videos you have no interest in, purely because it’s garnered near universal interest from other humans, and YouTube knows that you also are human, and might likely be interested by it. And given how you clicked on the video to post a comment, I’d say pushing this video onto your suggestions page worked.
glad i’m DNR
THIS IS SO INCREDIBLY HELPFUL!!! THANK YOU! also here bc of coronavirus 🙂
Why do you care about this if you are a dermatologist? Most people go in to dermatology because they want to have nothing to do with ICU and ventilators and critically ill people.
If you DIDN’T have a ventilator – could you use an IRON LUNG instead?
Iron lungs are hard to find. They cannot find parts for the old ones that are still around. But it was helpful in the past especially for Polio patients.
My breath rate is usually 55-56 per minute.
My cat loves the doctor’s voice, and though usually very active, is sleeping nearby.
Me too – zzzz
I wonder if the poster has heard of this new-fangled thing called a camera, or if he is just having too much fun in MacDraw to bother showing actual photos or video of the equipment he is talking about?
Im here to learn about ventilators because im going to volunteer to repair these machines at my local hospital
@James McLain Drager Germany
@Johnny Two Hands it’s a noble thought for sure, and it is not rocket science. More like HVAC or possibly electronics, which a lot of people have experience in. Most people are capable of learning how to do simple repairs, and cleaning. If they want to volunteer at the hospital, Bravo! I’m sure there are plenty of jobs to do!
@James McLain It’s really not like that…there are different types of ventilators for different areas of care and different needs; ICU vs NICU vs OR vs home setting, etc.
Gees I hope you’ve had experience with ventilators!
Good luck. Let us know how it goes. Anyone know what company makes the world’s best ventilator machines?
Elon and Tesla engineers are scrambling and watching these videos.
Dont buy a Tesla one they may decide to black list your model, and leave you gasping for air.
Only took the guy one trip to local library to become a rocket science, literally!
MedCram is gonna blow up over the next 3 months.
Just like the virus.
Disconcerting that the lungs look like tombstones. Unfortunately, somewhat apropos.
yeah, we’re all on house arrest in the United States
Nah, a true “lock down” means every road is physically blocked; Every entrance is guarded 24/7; One household can send one person each week for two hour grocery shopping trip, with application and approval and every move is electronically tracked in real time! And every violators having their front door welded shot, literally! With food delivery of course.
Don’t you have to go to work? 😨
Excellent – just learning about ventilators as we are working on a new lower cost design for hospital / home use for patients just needing a little assist – physicist Dave
Im in wt you frm winnipeg
Are you planning to do it amateurly and how many people are there working with you ? I am also interested.
Deep sea divers use liquid breathing. Could liquid breathing be used to save patients with severe pneumonia?
Who else is reading the comments in 2020?
That RONA brought me here
Who else is here because of Corona Virus?
Me too
Lol you just cracked me up. I work in a low key clinic for 5 years so I am a little rusty
Dennis Hoagland Hn he a bitch
@Diego Marquez good teacher
Dennis Hoagland Bc a teacher is using this video as an assignment
Who’s betting this video becomes even more popular
@Ram BO no.
The house always wins.
Can I leverage my bet 100*
i m R.N .i m reminding things again..
I am here because i just bought pneupac 2
I’m here because of coronavirus, ☹
Question…… God forbid the worse happening, could a hallway be lined with ventilators attached to patients? Not a pretty thought but COULD it work?
They did this in Wuhan, China.
A Consultant Psychiatrist in UK -here in preparation to help patients if needed by supporting them on ventilator
Not a doc but here because of the covid-19, very interesting, I supposed nowadays ventilators have an automatic setting set by a determined preset.
Extremely interesting about ventilators
Thank you for these excellent and informative videos.
Very intresting thanks for sharing.
Can you use a vpap machine to treat pneumonia systems if in an “extreme emergency situation”? Asking for your personal opinion, not professional doctor opinion and you are not liable for your comment. Lol;) I want to buy an 02 generator but I found a vpap for a reasonable price and want to prepare….
In the CV19 world yours is an excellent question. I have a technical engineering background and also severe sleep apnea so I am very familiar with CPAP, VPAP and BiPaP machines over the past 14 years. Trying to evaluate whether CPAP/VPAP machines fed with supplemental oxygen into a full face mask (o2 concentrators in the home or hospital oxygen) could be pressed into service to handle SOME of the ARDS CV19 patients. I hope some engineer at ResMed Inc is asking the same question and exploring the possibilities.
My concern is that normal ventilators are complex machines because in a hospital setting the desire of ICU staff (and administrators, legal departments) is to have a one machine that can be made to fit all patients needs by using multiple control settings and enough variable modes. CV19 unfortunately may overwhelm the healthcare system’s limited supply of these complex “one-size-fits-all” ventilators. My hope is a significant fraction of CV19 patients with ARDS might be treated effectively with already mass produced lower tech, but still very capable modified CPAP machine. If even 50% of CV19 patients could be supported by a modified CPAP this would free up more versatile standard ventilators for more problematic ARDS patients.
How to clear legal issues and bring modified CPAP technology into service in an industry which traditionally resists creative problem-solving not backed-up by multiple years of expensive clinical trials, is maybe harder to solve than the technical engineering issues.
Please copy this reply on other CV19 blogs should you think this question is worth investigating.
What?
AC is actually a name strictly used by Puritan-Bennet ventilators and akin to calling all tissues Kleenexs. CMV is most accurate name to use. Just clarifying this because there is a lot of confusion with ventilator nomenclature.
Thanks , very helpful .
Great teaching
If you have respiratory problems like I do here New Zealand in the Timaru Public Hospital you would be dead within 5 minutes apon arrival
Like they even have great difficulty treating Pneumonia and I kid you not
very clear explanation, coming to read this lecture as i’ve read that the wuhan virus patients are subjected to mechanical ventilation treatment
I’m not in the medical field at all. Your videos are extremely well explained where an engineer can clearly understand the lesson that you are teaching.
Yay learning!
Nice and simple; thank you so much for making a difference in our practice and hence, the lives of many grateful patients!
Great video! I LOVE MedCram content! I’ve been making similar videos, inspired by you guys. Keep up the great work, MedCram!
informative
Thank you 👌👌👌
Thank you
thanku sir….a lot of help…we ll remember u till life…
Thank you so much! Learned a lot, especially as a student, who is thinking to go to the anesthesiology residency and, at the same time, working in ICU, I understand much more with your help!
@MedCram – Medical Lectures Explained CLEARLY Hey Doc! Can you tell me please if a vpap machine could work in a pinch in an emergency situation if you do not of an oxygen generator? Just your personal opinion? You are not being held accountable for your opinion, I want to assure you- just want to know if in a “world is ending” scenerio if this could POSSIBLY help deal with the symptoms, wink wink
Thanks for your comment! We wish you luck!
GREAT VIDEO
Amazing!
Amazing, thank you!!
wow it is very fantastic and i hvae got alot of knowledges from this lectur video
terrible lecture, aimless and pointless
Thank you! This is so helpful!
Fuck yeah thanks for sharing
great video, helped a lot
Glad to hear it helped! Thanks for the feedback.
I’d love for someone to answer if a patients triggers a breathe if the breathing cycle continues as prescheduled or resets breathing schedule.
In other words; if patient breaths in between scheduled breath is it going to lead to hyperventilating the patient?
@Kenneth Dique Your patient can absolutely hyperventilate in PC-AC or VC-AC. This is why RT’s manage ventilators, they know in-depth about mechanical ventilation.
The patient can be hyperventilated if they continue have respiratory efforts and trigger the delivery of fully supported breaths. It does not reschedule the breaths that are set.
It resets the breathing schedule. No hyperventilating
i was a patient on this treatment, i would just like to thank all doctors and nurses, and cleaners, they all do a fantastic job, god bless you all.
Sorry. Doctor Seheuld
Thank you very much for all of these videos doctor Roger Scheuld.I am an anesthesiologist and I am working in the Amazon Region (Roraima)..I am very thankful .
thanks a lot for these clear explanations
This was so helpful! I am taking my Anesthesiology final in a couple weeks 🙂 Thanks again
WOW, THIS CARTOONS IS VERY INFORMATIVE
I really enjoy your videos, Roger. Thanks for sharing and making so many things easier to understand!
I am leaving a huge “Thank you” here, I am working currently in Germany and this series of videos really help me to understand those differents modes of a ventilator! Congratulations for your nicely done and excellent work!
Same here
Super great 👍🏼. Thank you
This is really good!! Thank you!! Great teach for ventilator nurses!
Thaaaanks!
Great teaching. Very simple to understand. Thank you.
Thank you for the feedback!
An update to tidal volume. It is no long get 8 ml/ kg ideal body weight. It is now about 6-8 so 8 would be the max tidal volume. I choose the middle 7 so you can go up a bit and down a bit. The slightly lower tidal volumes are to protect the lungs. Max is now 8
+Brian DeLuca and prone!
+Brian DeLuca right. Start at 8 and get down to 6 as much as possible.
thank you so so so much
thank you
This helped a lot. I took CCP in the summer and that was the hardest class I’ve ever taken so far. I still struggled to understand the basics of the vent and so far your video has helped cleared some cob webs lol.
Very simple & nicely explained. Thank you.
I like the way he says ‘ ventilator’ !
This is AWESOME!!!! Ty!!!!
How Many Doctors Here Hit Like👍
Hi Medcram, I have throughly enjoyed listening to your videos on ventilation. I have an interest in producing educational videos and just wondered if you might be able to tell me which software you use to produce your handwritten videos? Any tips or further information you might be able to share about your creative process would be very gratefully received. Many thanks, FreeAnaestheticTutorials
thank you for your detailed explanation!
Your way of explaining difficult things with simple words is really gorgeous .. I love it ..
Gorgeous LOL
this was great! I’m a nurse new to critical care and vents have been confusing the hell out of me, this is making it more clear, thank you!
thank you, very useful and easy to understand video, I came here looking for a video to explain to me CPAP PPV PEEP PIP and i hope i find it in the next parts or in other videos on this channel
Did you find it
And sometimes there are even knobs on the non-patient-side of the machine 🙂 Very useful vid (as always)
nice explained 😉

Thank you so much for this lecture. It raised my Competency in Mechanical Ventilation by 40%. In home health it’s very important I not only know how but can explain the rationale
Ventilator knowledge for retards,
Thank you
please make a video on anesthesia
thank you for your help
Yes, it helped a lot.
Thanks
Assist Control is not the same as CMV…CMV the patient does nothing
@B Kang Yeap and it sounds like you are definitely an RT as well! Big difference between continuous mandatory ventilation and assist control. This was an overall terrible lecture.
8:29 Assist-control and continuous mandatory ventilation are not one and the same. There’s a big difference there. It’s called assist-control because the patient triggers the breath and the machine assists the breath and cycles it. Continuous mandatory ventilation would mean the machine does all the triggering and cycling of the breath.
+Kayla Roberts Continuous mandatory ventilation (CMV) is a mode of mechanical ventilation in which breaths are delivered based on set variables. … Thus, today’s CMV would have been called ACV (assist-control ventilation) in older nomenclature, and the original form of CMV is a thing of the past. Wikipedia- Continuous mandatory ventilation.

Nice breakdown/intro to vents
doc..ur understanding of the science and the way u made me understand it.. is marvellous..bow down to u sir…
Nice video. Thank you for the good explanation!
Great presentation! Simple explanation of a serious situation
It is a good presentation
Wow…from india
Great stuff, I am an ICU RN and am always learning new concepts, procedures and perspectives…still, the face pace to the ICU leaves me little time to quietly ponder and dissect all the information, and that’s were these short videos really help me grasp the concepts fully. Bottom line, many thanks!
Hello there. I have question. If a patient with a mechanical ventilator crashes, do you switch to hand oxygen (ambubaging) or just let the respiratory therapist do some adjustments with the MV?
Você poderia colocar transcrição para não-americanos. (You could put transcription to non-Americans, in english).. I’m from Brazil. I’ve studied english. Thanks.
thank you very much
this was helpful
That was really helpful, Thank you so much!
I wish you are in New York.
So helpful.Thankyou
Great info. I’m gonna have to use you form of explaining (which is fantastic) when during MICU rounds for my medical students and new interns rotating through our service.
what mean postive pressure and negitive
Way more than vent 101…
Very helpful!!
Very good lecture. However, I’m not thrilled with the amount of time watching the sketch show. College lecture meets pictionary? It could be more concise.
nice sr
As good and as simple as it gets!!
Good job 👍🏻
Thank you for sharing your knowlegde in such a simple and concret matter, please continue to add on value on healthcare education. Keep it up !🤗👏👏👏
Your videos are always helping me a lot to understand every kind of topic….thank you very much….
very helpfull
it is very helpfful for me.thank you!
thank you, it was very clever and simple
thanks very informative!
If AC is set volume….what is AC/PC. In the unit right now and one of the patients is on AC/PC with set pressure control and tidal volume is the dependent variable. This presentation, however, says tidal volume is fixed in AC.
Please note that AC does not imply volume ventilation. AC refers to the breath trigger as was explained. The breath can be cycled or terminated via volume, pressure, flow control, or adaptive/hybrid controls. It’s a matter of what starts the mechanical or machine-delivered breath vs what ends it. It should not be assumed that AC is only used during volume ventilation and is somehow different from or unrelated to pressure ventilation.
zokrab—- excellent teaching! thanks.
erebusnux121 this sounds like PRVC which is a volume targeted mode that limits the pressure to 5 below the set upper pressure alarm limit. This mode is wonderful because it protects the lungs, but also allows for a targeted volume.
such a great help
Excellent series!
Thank you
excellent presentation.
Vents made understandable. Thank you!

Lung compliance= stretschiness of the lung
great lecture
Thank you!
you CLEARLY explained it, indeed!

Good to hear, thank you
Your a great teacher, thank you so much for the video’s, I really appreciate them. 🙂
Thank you for the videos, they are so helpful in understanding ventilators! It would be great to see a video on SIMV, and VC + (PRVC) in the future!
diablillocable. gracias
Thanks! Clear and concise.
You guys are awesome! I’m so glad I found this channel! Cheers from Israel

Thanks for the support from Israel!
Thanks. Very helpful!!
Strong work guys! Love you lectures. Trying to get through them all!
+Jim Mathey Thanks Jim! Hope you’re doing well
great work thanks alot
Thanks
simply you are awsome, I am really thankful for your helpful vedioes
+zahra tmtm Thank you for the comment and feedback
you are amazingly awesome
I’m sorry for my confusion, but I thought that CMV and AC were two different modes of ventilation?
Exactly. In CMV the vent triggers a breath whereas in AC the patient does..
+Jaime Scheiner Thanks for the question- they are the same mode just different names.
very nice lecture informative
Awesome! 😀

Love this lecture. Very clear and it really corrects my wrong perception about ventilation mode. Keep it up!
+Andy Bai
There are a few factors in sleep apnea treatment. One place I discovered which succeeds in merging these is the Stans Slumber Method (google it if you’re interested) without a doubt the most useful resource that I’ve seen.Check out all the amazing info .
+Andy Bai Thanks for the feedback!
You make it seem so easy. That’s awesome even tho is not easy at all. 🙂 I am a new ICP and my portfolio includes ICU and CCU. I find ventilation very challenging for now but hey, I just started on my own a Week ago. Soon I’ll have to start the CLI and VAP program. I read CDC and PIDAC documents. Any help there? Thank you.
It,s really helpful ,thanks
basics nicely explained!
thank you, your videos are really helpful
Pulmonary compliance (or lung compliance) is a measure of the lung’s ability to stretch and expand. In clinical practice it is separated into two different measurements, static compliance and dynamic compliance. Static lung compliance is the change in volume for any given applied pressure.
Static compliance is how the parenchyma/alveoli in the lungs are doing. Dynamic compliance is how the entire lungs are doing
+Gee Cy thank you so much!
+Saad Butt The difference between dynamic and static compliance was dependent on alveolar pressure
application of dynamic respiratory mechanics as a diagnostic tool in ventilated patients should be more appropriate than using static pressure-volume curves.
+Gee Cy and dynamic?
Wonderful video
Thank you!!
Excellent presentation! Quick question: which program did you use to make the this lecture?
+javy888 Thank you- front cam and smooth draw 4
thank you very much..this is magic..you saved me 🙂
+Halla Elhosainy Good to hear- thanks for the feedback
thank you so much <3
thanks a lot …
Thank you very much for this wonderful illustration of such a complicated topic
+Ahmad Shokry Thank you for the comment
Where have you been all of my nursing life! I work in a pediatric vent facility with amazing RT’s who try their best to explain settings/modes/ functions to me, but since I have them, I never found it necessary to ‘know it all’. Now that I care for a baby at home on mechanical ventilation, although my education/experience has taught me everything that I need to know care for him, I just want to ‘know it all’ !! You explained mechanical ventilation in such a way that, now, my RT’s smile in amazement when we converse 😉 thank you so much!
+Linda Ellis Thank you for the great feedback!
NYC work 🙂
Best video on YouTube !!! Very informative
+Melody Aribuabo Good to hear- thank you
Awesome vids!! Subscribed!!!
+Shruti Mani thank you for your comment and subscription
even after you helped me through PA school, I still watch videos like this as I practice.
+Matthew Kele Good to hear, glad the videos remain helpful
Thank you!
Quite the artist
I had to create a you tube channel to make a comment / request …. Please do a video on ICP head injuries / meningitis In the critical care setting … I’m a 4semester RN student wish there were more of your great videos … Thanks!
@Lali B Thanks so much for the topic suggestion, we will put this on the list. Best of luck in the rest of your training
Thank you for the easy-down to basics demo!
@Paracutie thank you for the comment
Winderful video’s I am certain it will help me with my boards this month
If you’re an RRT you should know ventilators inside out… this video is a refresher for people who aren’t RRTs lol
Thank you
so much
Excellent especially for students and doctors from non English speaking countries. The usual video tutorials given by native English speakers is with heavy accent and difficult to comprehend and causes lots of stress trying to make out what the speaker is trying to say. But your accent is so clear, slow, English is so simple and you have done fantastic service to students from third world countries. Even a layman can understand your lectures. If the patient care improves because of your lectures,(I am sure that it will) the credit actually goes t o you.
very helpful, thank you!
thanxxx for this informative video
thanks for vid…
Thank you! It’s very helpful.
I work in a home care setting and my client is on a ventilator (non-dependent). This series was very helpful to understanding the vent dynamics. Thank you!
what do you mean by “non-dependent”?
@Deena Foote Glad to hear the series helped with your understanding
hi megan …where u from
You guys are awesome! Very informative!
@GrizzleyBruin Thanks for the feedback- glad the video helped.
I love you, so awesome!!!
Great Vid!
awesome sir. really great video
Awesome buddy…liked the simple methodology of teaching ..didn’t cram it up like the docs do it while explaining the paramedics..thanx again…concept is crystal clear
@Johnson Irudayasamy Thanks for the feedback. Glad to hear it helped
THANKYOU VERY MUCH 🙂
@snowbunny378 you’re welcome- thanks for watching
very informative, i am starting my IM residency and these lectures made a great difference to my knowledge , thanks
@Hosam Eldin Bebars Good to hear. Hope your residency gets off to a good start
Thanks again!
First, thank you so much for sharing your knowledge and making it understandable to the novice. Although I can’t put most of your instruction to practical use in my own job, I appreciate the insight it gives me into the challenges you face in the hospital setting. Quick question, am I missing something or did you not touch on SIMV mode? I watched all 5 parts and if you covered it, I must have zoned out. When you described AC, it sounded like SIMV with the patient triggering the breaths as opposed to CMV breaths being vent-triggered. I realize the videos are finalized, but could you explain (as you do so eloquently) the mechanical difference between SIMV and AC mode? Thank you!
AC mode will deliver a consistent volume when the patient triggers a spontaneous breath, hence the “Control” in Assist Control. SIMV will still give the patient a set number of controlled breaths, but the patient triggered breaths (spontaneous) will be as big or small as the patient makes them (not controlled). AC = vent controlled spontaneous breaths while SIMV = patient controlled spontaneous breaths.

Great lectures on air!!!
I have used your lectures to help prepare myself for Nurse Anesthesia school interviews, and to obtain a better grasp of certain subjects. I have been accepted into the 2015 class and I want to take this time to thank you for all the great instruction you have given me through your lectures.
How did it go?
That’s awesome! Never stop. So great to be part of your education!
CANAYAMD VC and PC are two different modes. They do have variations which add assist control for example ACVC+, ACPC, VOL/AF(seen on my anesthesia machine). But strict VC or PC have set values that do not assist a spontaneous breath. There is no pressure support setting on strict VC or PC. However you can assist with modes like SIMV, ACVC+, and of course pressure support. ACVC+ is essentially pressure regulated volume control, so you can deliver a set tidal volume with variable inspiratory pressure to account for changes in lung compliance thus hopefully minimizing your peak inspiratory pressures..hope I answered your question:)
mrfrizzle0782 I thought volume control and pressure control are modes of assist control. You are equating assist control to volume control. Know what I mean?
