COVID-19 Ventilator Course: Learn or Review Mechanical Ventilation (Free at

Critical care specialist Roger Seheult, MD illustrates a concise review of the essential skills of mechanical ventilation. We’ve made this video series free at

As communities across the world are facing or preparing for increasing numbers of patients in respiratory distress from COVID-19, MedCram has packaged this video series for clinicians and hospitals on the frontlines.

We understand that medical professionals (and students) that don’t have significant experience with mechanical ventilation may be called upon to help ventilator management teams in critical care settings. And clinicians with extensive ventilator experience may want a refresher or a tool to aid in teaching mechanical ventilation strategies to other clinicians.

This video series is a collection of previously recorded MedCram videos on mechanical ventilation with the addition of some COVID-19 specific videos.

This course will remain free, please share it with anyone you think may be interested. We hope you find it helpful, and we welcome feedback.

We appreciate you – medical professionals, students, and volunteers around the world. We are in this fight together.

    Ventilators are the key resource to saving lives in the fight against the coronavirus , but they are useless without physicians, respiratory therapists and nurses. Thank you !

  2. Jane Threes on June 7, 2020 at 4:43 pm

    you all need to read up on oxygen toxicity to understand why ventilators are not great for our health
    The lungs are a wet system
    Medical oxygen has only 67ppm of water contamination
    The lungs require 100% humidity- that’s saturated air
    The lungs are collecting water not oxygen
    That’s the medical misdirect!
    The RBCs are loading water not oxygen
    Lungs perform a Rehydration process and maintain blood pressure

    Just need to think about how effective humidifiers are with salt and iodine
    In comparison to oxygen
    Humidifiers have no side effects
    While oxygen supplementation can be deadly

    Premi babies were put into 100% oxygen tents and had their lungs injured and they were blinded – all from oxygen’s power to dehydrate.

    The babies eyes dried up – our eyes give up moisture (foggy glasses) and take in moisture from the environment.

    We are a salt water system

    Salty blood, sweat, tears, urine

    A saline iv can replace blood lost.

    Oxygen is a manufactured product – very very very dry compressed air.

    Thank you .
    Thank you.

  4. Andrew Souther on June 7, 2020 at 4:44 pm

    I’ve done 4 things to greatly improve my lung function and overall wellness. My sleep, energy, and life outlook are greatly improved:
    1. I started using the BreatheEasy Lung Exerciser about 5 years ago and still use it,
    2. I stopped mouth breathing unless absolutely necessary, even when exercising, nose breathing is part of the immune system,
    3. I did light mouth taping at night in order to ensure nose breathing all night,
    4. I do a simple exercise to reset my CO2 levels for triggering breathing so I don’t breathe so much. See Patrick McKeown’s work for more about this. Voila!

  5. Barbara B. on June 7, 2020 at 4:44 pm

    This is a very informative video – thank you. I do have a question though. A few years ago I had a partial thyroidectomy to remove a nodule. My left recurrent laryngeal nerve was cut and left me with a left paralyzed vocal cord. I have since had an injection to bulk up the vocal cord, but my left side is now in a permanently closed position. Should I ever need to be incubated, does that mean that a tube that would be used would automatically ‘plow through’ my vocal cord and again damage it, resulting in inability to speak again? Or can patients be successfully intimated with one-sided vocal cord paralysis? Of course I understand that in such instances ability to breathe trumps all, both just the not knowing is causing me some anxiety.

  6. Sydney De Angelis on June 7, 2020 at 4:45 pm

    Thank you for all your videos, Covid and beyond. You have been a source of reliable, easily understood information in the midst of chaos. This ED doc is very glad you are taking the time to put out these videos

  7. Janice Phillips on June 7, 2020 at 4:45 pm

    Thanks Doc! Great info for those out there kicking Corona’s Ass and saving lives!

  8. Юрий Тихонов on June 7, 2020 at 4:46 pm

    What pressure range in mBar should the device give out ??? Tell me please.

  9. Nicole M on June 7, 2020 at 4:47 pm

    WARNING – I strongly suggest that everyone sign their DNR forms. You definitely do not want to have a tube shoved down your throat. Life is not that great or special to undergo that torture. It is the worst kind of torture. Imagine not being able to breathe for like well past what you can intentionally do. When the panic and sense of suffocating is at it’s worst, that is an exact snapshot of what the ventilator will feel like the ENTIRE time. Imagine those worst moments of not being able to breathe, sensing no lung movement, only experiencing that for days. It’s like being eaten alive only having your flesh regrow so you are permanently being eaten alive, or suffocating in this case. Ventilators take you to the very cusp of suffocation and leave you there for days while you mind and body are screaming. I’d imagine that over 50% of people that are forced to suffer through that torture have their minds broken to one degree or another. It’s like the worst moment of water boarding X100, frozen in time and stretched out for days. We should ventilate terrorists to learn their secrets, not something is sweet and kind as water boarding.

  12. Football For life on June 7, 2020 at 4:49 pm

    what is the value of the compliance that we need ?

  13. Aberu on June 7, 2020 at 4:50 pm

    What’s your assessment of Nvidia’s Chief Scientist’s design?

  14. Maureen Gerrity on June 7, 2020 at 4:51 pm

    Great course! However link to download cme certificate did not work. Any suggestions?

  15. Liviu M on June 7, 2020 at 4:52 pm

    Doctor, can you show an actual ventilator, possibly several examples of it and how it operates? I have sleep apnea and my main worry is that if I, or someone with a similar respiratory condition contract Coronavirus, it may be a death sentence. I am also contemplating purchasing a cpap machine.

    Sorry, is this the first of a series? Where can I find the next?

  19. Angel Ng on June 7, 2020 at 4:54 pm

    Thank you for the valuable lesson

  20. Afsmita Shrestha on June 7, 2020 at 4:57 pm

    Hello medcram, I am a medical officer of Nepal I am very much interested in this course. But I couldn’t find for sign up.

  21. Doug Benchley on June 7, 2020 at 4:59 pm

    GREAT Videos – I’m not in the medical profession but an engineer and your videos clearly define Ventilators – thank you for that . . .

    Had a question . . . .the COVID -19 virus causes swelling in the lungs – one treatment for swelling is adding ice or cooling down the affected area – would it be beneficial to cool the air going into the patient’s lungs to a point to help reduce the swelling? . . . if so have we tried doing this to help people infected with COVID – 19?

    Thanks again!!!

  22. Mathew George on June 7, 2020 at 4:59 pm

    thank you for the clearly explained lectures

  23. Cameron Potts on June 7, 2020 at 5:00 pm

    That’s why they cost 25 thousand dollars wow

  24. Mary Corder on June 7, 2020 at 5:01 pm

    Heading to NY to a setting where I may need to be assisting in more vent management than what I am typically used to. Thank you for this.

  25. Eric T on June 7, 2020 at 5:03 pm

    Every picture ive seen picturing a person on a ventilator . They are all on their backs. So i guess they are twice as likely to die. Even your diagram has the person on their back

  26. jayde M on June 7, 2020 at 5:04 pm

    Excuse me I think there mite be something wrong with the hemoglobin / try copper 1 as a helping supplant

  27. the reflectional analyst on June 7, 2020 at 5:04 pm

    I’m not even a doctor but this was so enjoyable to watch. Neat, understandable and straight to the point, no sophistication. Keep up the good work, work that may save lives indirectly!

  28. Justin Chan on June 7, 2020 at 5:05 pm

    Wow, this is so great to learn from . I am an optometrist and my mother is now on a vent from COVID19 in Michigan right now. I feel that I have a far greater understanding of what is going on now.

  29. Steve Lenores on June 7, 2020 at 5:06 pm

    ~20% survival rate for those put on a ventilator whom have covid-19. Hydroxychloroquine has an ~80% cure rate in early trials. Use the drug first (preferable when you are moderately ill when it is most effective) and then if it doesn’t work go to ventilator if necessary. Increases your chances to 84% of cheating death (beats 20% IMHO). Discuss this with your doctor in you are moderated ill with covid-19. (Note: I’m not a doctor so take this for what it is worth.) I will discuss this with my doctor if I’m unlucky enough to get this nasty disease. The actual best advice is not to get sick in the first place.

  30. Sidney Brown on June 7, 2020 at 5:08 pm

    God bless you guys! I am an RN without vent experience but I want to help – excited to learn ASAP

  31. Mr. Drive kay on June 7, 2020 at 5:09 pm

    So this basically do not help to cure the disease. It’s only help the paints to breathe until he or she dies or live! In another word, good luck. If u are lucky this machine with save you. If not . God bless your soul.

  32. Made You Look! on June 7, 2020 at 5:09 pm

    About to cop one these homie

  33. Nada Emad on June 7, 2020 at 5:10 pm

    which mode of ventilator most useful with covid 19 patient ???

  34. T W on June 7, 2020 at 5:12 pm

    Thank you Dr. Roger Seheult😊

  35. henrik chr on June 7, 2020 at 5:14 pm

    i miss more info on oxygen treatment (manuel/automatic ex. O2matic) for covid-19 – which potential can lower the need for use of a ventilator as explained nicely in this video

  36. ᕱ⑅ᕱ on June 7, 2020 at 5:15 pm

    I’ll never work in ICU but it’s good to know about it

  37. Oscar Banuelos on June 7, 2020 at 5:16 pm

    Thank you Professor Seheult!

  38. allan strand on June 7, 2020 at 5:18 pm

    NEW-4 patients on the same respirator !!! -The solution is called Ventsplitter and is an open-source code solution for 3D printing. The idea that several patients could potentially share respirators Microsoft News.

  39. Susan Black Andrade on June 7, 2020 at 5:21 pm

    Thank you for your time and forward thinking without any political or personal gains.
    God bless you!

  40. Candice Ramsey on June 7, 2020 at 5:23 pm

  41. Justin Dougherty on June 7, 2020 at 5:23 pm

    Could they use cans of air to stand in for ventilators that they don’t have. Pressurized cans of air used for hiking and diving with millions of cans already made…. but how to use them in place of the machines. If they can figure that part out, it may solve the whole problem of not having enough breathing machines…..

  42. rmfyi on June 7, 2020 at 5:25 pm

    Can you survive after being on a ventilator? People tend to stop breathing and die soon after a ventilator shuts off, though some do start breathing again on their own. If he is not taking in any fluids, he will usually die within several days of a feeding tube removal, though he may survive for as long as a week or two.Jul 21, 2019  
    Can you get brain damage from being on a ventilator? Researchers find why ICU ventilation can cause brain damage. Patients who have been mechanically ventilated in intensive care units have long been known to suffer some form of mental impairment as a result. … They note that the incidence of delirium in patients who are mechanically ventilated is around 80%.Sep 26, 2013

  43. CPM ENGLISH ACADEMY on June 7, 2020 at 5:27 pm

    this is very useful all of you want more information about this ventilators…? I watched a video one channel it`s
    awesome like this…if you free, follow "doctor rishi" channel

  44. Marwa Elrayes on June 7, 2020 at 5:33 pm

    The site can’t be reached 😔

  45. JJ on June 7, 2020 at 5:33 pm

    Truly amazing how many Chinese Bots in the comments!

  46. Divya A on June 7, 2020 at 5:34 pm

    I wanted to ask if the critical COVID patients are sedated when ventilation is applied or not? I saw a video where a critical COVID patient was successfully treated when mechanical ventilation was applied to her in a sedated state. (Singapore)

  47. Lauren Owlet on June 7, 2020 at 5:36 pm

    What about ECMO?

  48. Anthony Brown on June 7, 2020 at 5:36 pm

    Could you rig cpap Machines to help with shortage?

  49. Otavio reis on June 7, 2020 at 5:37 pm

    I’l would do like to know if a simple project will be efective in a emergency scenario. I have a project using just soleids valves and no contol PEEP.

  50. Debbie Z on June 7, 2020 at 5:37 pm

    So in my mind it’s possible for patients to be grouped together according to lung compliance and pressure to potentially share a ventilator in a severe shortage. I watched the video of the doctor in Detroit? Or Chicago— somewhere in the Midwest . How would you potentially improve on the multiple patient set up?
