See why over a million clinicians and students have watched MedCram videos on mechanical ventilation.
This video includes the ventilator modes of PEEP, CPAP, PS, and an illustration of the pressure-volume relationship in mechanical ventilation. Also, (learn or review) how to write mechanical ventilation orders (Mode, TV, FIO2, PEEP).
See video 1 of this series for a discussion on the vent mode of AC and compliance.
This video is part of the “MedCram Remastered” series: A video we’ve re-edited & sped up to make learning even more efficient.

MedCram = More understanding in less time
Medical education topics explained clearly including: Respiratory lectures such as Asthma, COPD, ARDS. Renal lectures on Acute Renal Failure, Urinalysis, and The Adrenal Gland. Internal medicine videos on Oxygen Hemoglobin Dissociation Curve / Oxyhemoglobin Curve and Medical Acid Base. A growing library on critical care topics such as Shock, Diabetic Ketoacidosis (DKA), aortic stenosis, and Mechanical Ventilation. Cardiology videos on Hypertension, ECG / EKG Interpretation, and heart failure. VQ Mismatch and Hyponatremia lectures have been popular among medical students and physicians. The Pulmonary Function Tests (PFTs) videos and Ventilator-associated pneumonia lectures have been particularly popular with RTs. NPs and PAs have provided great feedback on Pneumonia Treatment and Liver Function Tests among many others. Mechanical ventilation for nursing and the emergency & critical care RN course is available at MedCram.com. Dr. Jacquet teaches our EFAST exam tutorial, lung sonography & bedside ultrasound courses. Many nursing students have found the Asthma and shock lectures very helpful. We’re starting a new course series on clinical ultrasound & ultrasound medical imaging in addition to other radiology lectures.
Recommended Audience – Medical professionals and medical students including physicians, nurse practitioners, physician assistants, nurses, respiratory therapists, EMT and paramedics, and many others. Review and test prep for USMLE, MCAT, PANCE, NCLEX, NAPLEX, NBDE, RN, RT, MD, DO, PA, NP school and board examinations.

Beautiful
Can anyone tell me why PEEP does not result in an element of ‘re-breathing’ ? Or if it does? If there is an artifically-applied residual pressure at the end of expiration then that pressure must be coming from a volume of gas (Boyle’s Law, right). That volume of gas is going to become higher in CO2 and lower in O2 with every breath (i.e. being rebreathed), despite there being an element of diffusion/mixing with the new gas coming in with each inspiration? Or is this the wrong way of looking at it? I understand that there is often a transient hypercarbia with the application of PEEP and wonder if this is reflective of this ‘re-breathing’ that I am referring to? Any help, greatly appreciated.
So what I’m getting is PEEP and PS are best for Covid19, since the virus attacks is your lungs alveoli and damages them the most. Thank you for your info.
I am about to start the last prac of my BSN in ICU and love these to help me wrap my head around what I will be learning before I get there. Thank you for the clear explanations.
thanks .. but is the peep measured in cmH2O or mmHg
thankyou a better explanation than that which I used to build DIY ventilator, very interesting.Shame I didnt see this 2 months ago lol
Essential info. best explained for non resp. med staff, operating ventilators during Pandemic .Thank you
My husband is watching this. Can I modify a BiPAP machine to act as a ventilator for COVID 19 surge
Amazing video. Thanks to Corona Virus, your videos are coming to fore! Keep up the good work, Doc!
EXAUST AIR TO ATMOSPHERE FRON ANY HOPITAL TO BE EITHER DRY AIR WASHED SYSTEM OR AIR WASHER SYSTEM . IF NOT THE CORONO VIRUS CAN SPREAD THRU ENTAIRE ATMOSPHERE. EXHAUST SYSTEM MUST KILL ALL VIRUSES BY CHEMICAL PROCESS VETILATOR SYSTEM. MUST BE. AIR CHANGES TO VENTILATOR 35 -40 AIR CHANGES. SO2 CAN BE INJECT THRU AIR EXHAUST SYSTEM TO ATMOSPHERE.

Excellent video. These are useful for docs that do not normally run ventilators, but may be called to do so, with the COVID pandemic
So, I’m a bi pap user and Ive been talking to anyone that’s willing to listen that these bipaps might be the poor cousin option for a ventilator, since we are short a few hundred thousand vents, and the cost is 40k give or take and the bi pap or the apap could be very useful at approx. 2k a piece, why would we not use these as a bridge? Please explain pros vs cons.
So can I use my CPAP machine for COVID?
audio quality is terrible. constant background echo
Hello Doctor, these are really good clear videos. I’m an engineer trying to get a grip on all this for the purposes of understanding the requirements for emergency ventilators
Would it be possible to edit the video titles with a numeric sequence? This should help learning everything in the most useful way. Or make up an ordered list? Many thanks again
The best way to get this information really dialed in is to work for or intern with a vent assisted person in the community. We are very active individuals and look for cool detail-oriented individuals who we train on our type of ventilator, settings, and accessory equipment. You need to know your client ventilates and quickly problem solve if the alarms sound or a tube disconnects.. After a while you will be competent and confident working around people on vents and especially conscious people who use ventilators in the community. We’re also pretty cool if I do say so myself 🙂 !
And here I am using my own lungs like a sucker. – Homer Simpson
Hi. What is the most difficult aspect of ventilator construction?
I use a bipap and I have an extra old CPAP. Should I give it to a local hospital. Should I save it for a family member is they get the COVID? Would that work?
How do I put that I love this videos? I can’t! and I just love them! Amazing thanks!!!
why does the flow go below zero?
Breathing out
this is awesome, simple and elegant. many big thanks!
Thank you so much
You’re welcome.
I learned more from these videos than from my professors.
If the peep is set, how come the pressure goes negative at the end of patient-triggered respiratory cycle(as shown in the first two examples)?
I think it’s because when the patient attempts to breathe, in other words sucks in the little bit of air that remains in their lungs, the sucking with no result (due to ET tube balloon and they can’t take their own breath) then causes the negative pressure within the lung, at which point the vent senses the sucking / neg pressure and delivers the air
@Kevin Green Patient sucks in air (tries to take a breath naturally), then the ventilator starts serving more air than the patient is currently able to take in, thus upping the pressure. So it only drops below for the brief moment between patients brain wanting a breath and the ventilator reacting.
That was my question as well. Because the PEEP is already set at 5, the alveoli should maintain a pressure of 5 consistently.
When writing an order these are just the basic things that the physician orders, respiratory therapist set a lot more parameters to go along with it
Thank you Dr. Seheult, love your lectures
You’re welcome!
What is the main difference between PC and PS mode of ventilation? Just the fact that in PS, the patient needs to demand a breath, whereas in PC, the patient or ventilator can trigger the breath?
Thank you. 😭
EXCELLENT TEACHER
I love to put these on as podcast during driving 👍😉
be careful
These videos are always so concise thank you
Perfect video!
Fantastic lecture/video! RRT out
@MedCram – Medical Lectures Explained CLEARLY Yes i have and it is just as good as this one! This is my favorite medical YT channel
Thanks, we’re big fans of RRTs! Have you checked out our lung ultrasound course yet? https://www.medcram.com/courses/lung-ultrasound
We recently got AARC accreditation to offer CRCE credit for this course. We’ve had great feedback from RTs and RT programs on it so far.
