Thanks for watching. Get CME for this video series, AND see Dr. Seheult's updated vent videos at our website: www.medcram.com/courses/mechanical-ventilation-explained-clearly

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.

Thank you! I'm an ER nurse turned ICU nurse literally overnight. I know nothing about mechanical ventilation and tomorrow I get to work on the machines for the first time so this is a great series!! I couldn't find something like this in German (I work in Germany as well) but hearing it explained so clearly in my mother tongue helps me feel less nervous.

Who is here because they are the new nurse to the ICU unit.. 🥹

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!

Who's betting this video becomes even more popular

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.

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

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!

love the no nonsense terminology - as someone once said - the more you know about a subject the simpler you can make it sound

I’m a mechanical engineer and I love your videos. They are very interesting and informative. Thanks!

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!

Great video, perfect for ICU nurses like me who still struggle with understanding vents. Very easy to understand!

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!

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.

MedCram is gonna blow up over the next 3 months.

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

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 .

I’m a respiratory therapy student so I’m definitely looking forward to this

I am a total layman re ventilators. Your calm and well paced explanation is down to earth and I am sure anyone in the field will understand this. Keep up the good work,

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.

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!

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

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!

I was intubated a month ago due to multiple pneumothoraces as a complication from Wedge resection of my lungs. It’s a very traumatic experience but thankfully was able to survive.

Tell me you made it through covid.I have followed you for awhile now and I have found comfort in your courage and faith.God bless and keep you.

even after you helped me through PA school, I still watch videos like this as I practice.

This was great. I wish I had this available back in the day. Thank you for your time. I started out as an Oxygen orderly back in 1973 after I was discharged from The Marine Corps in New York City. Wheeling H tanks on a dolly with an adjustable wrench to the patients bedside and changing them out when they reached 500 PSI. No piped in Oxygen back then and only open patient Wards. with 10 to 15 patients in a room separated by a draw curtain.Part of my arsenal was a No smoking sign. It was not uncommon. to see patients smoking while lying in their beds as well as a doctor examining a patient with a cigarette dangling from the sides of his mouth. Oh how we long for the good old days LOL. I eventually became a certified inhalation therapy tech. Via The AARC later it became the NBRC or vice Versa. I stopped practicing in 1999 when I came to Massachusetts only to discover Massachusetts was a commonwealth and reciprocity of my licenses were never granted. I like to believe, I was a respiratory therapist and have been around since the Infancy of our profession. That makes me the original OG of respiratory therapy. Back in the days. We ran to codes with a Bird Mark 5 or mark 8 pressure ventilators ( the little green Box ) attached to an E-cylinder of Oxygen. The ideal settings on the Bird were 15, 15, 15. It was actually a great little machine to run to codes with. Easy to maneuver through patients wards and great during transports. Back then the big fear with the Bird was the infrequent incidence of Barotrauma as well as all the negatives associated with Positive pressure ventilators. However, if you knew what you were doing, You were golden. later in my career I became a clinical instructor and that became part of my introduction to my students. I would introduce myself and begin with these words ( Keep in mind. I am a United States Marine ) I would begin, If you are here to press buttons and turn Knobs. This is not a class for you. I can teach a Monkey to do that. However, if you want to know what happens mechanically and physiologically after you have pressed that button and turned that knob. Please have a seat. ( By the way, my students had the highest passing rate on certs and registry ) Back to the past. Back then, we had Engstrom and Emerson Volume ventilators with a heating plate at the bottom and a steel pot similar to a pressure cooker that sat on atop of the heating plate. The tubing ( AKA Manifold) contained steel wool lining the inside of the tubing to increase and help maintain the humidity of a dry gas. It had a huge mechanical spirometer. It sat on top with a large needle that move per cycle of respiration . One day, the workhorse came onto the scene. We all gathered around and received an Inservice on the latest and the greatest. The Puritan Bennet MA-1. followed by the 7200, the bear respirator, Etc. I could go on forever, so I will end here with these two memories. When PEEP was in its Infancy. Hell, it felt like we invented it. We would take a large bottle filled with water, placed alongside the respirator on the floor. We would submerge the tubings of the manifold into the bottle below the water level we would adjust the amount of PEEP by adding more water to the bottle or elevating or decreasing the height of the submerged tubing into the water. This is how PEEP. started out. ( Positive End Expiratory Pressure. prolongs exhalation. Thereby allowing the Alveoli to remain open longer and allowing for a prolonged period of Diffusion along the Alveolar Capillary membrane ) Somethings you never forget LOL If you took the time to read this. Thank you for allowing me to share with you a trip down memory lane. Trust me there is a lot more to share as my career span was well over 35 years working in diverse clinical settings and adult critical care. To include having the honor of being part of Mount Sinai's School of medicine and working as a pulmonary research technician alongside Dr. Irving Sellikoff ( asbestosis and Sarcoidosis studies) Dr.Alvin Tierstien and Dr. L.K Brown. Traveling the country back in the 80's as part of a research team to predominately gay communities and seeing well over 100 patients a day and performing PFT's and Perfusion studies when patients at that time were expiring in NYC and the diagnosis at that time was " Fever Of Unknown Origin " ( AIDS) Going into the Tunnels of the NYC Subway system with a team to locate and perform sputum inductions on the homeless. At that time, we had a strain of drug resistant TB. Then I moved to Mass and my carrier came to an abrupt halt because of Bureaucracy. "Sie La Vie" . I am a U.S. Marine. We are trained to adapt and overcome. I fell back on the trades. In the Marine Corps, I was formally trained as a Lineman and electrician as well as an Avionics tech.( Aircraft electrician ) At Marine Corps engineer school. Courthouse Bay N.C. My mechanical aptitude I believe was why I was able to teach my students and reach them in a mechanical way. I would equate the human body in its purist form. A machine and in a mechanical way. The neuron pathways are no more than a glorified electrical conductor ( wire ) picture the wiring in your home. It has copper and the insulation that surrounds the copper coil is made of a rubber non conductive material. A neuron for all intents and purposes is a wire and it's insulation it is the Myelin sheath. The heart, a four chamber pump. Positive and negative pressure outputs with valves that open and close and seal etc. I miss my career, I miss my patients, I miss being able to have that feeling after all is said and done. Watching that patient and his family go home together. However, I was able to vicariously share with you a very small part of the evolution of Respiratory Therapy from a first hand eye witness. This is the OG of Respiratory therapy saying Thank you again and Semper Fi.

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.

Amazing how impactful this is in the wake of Covid19 and seeing comments from practitioners years ago to present. Thank you, Dr !!

This is the exact explanation and step by steps instructions I was looking for. Please continued to do more blogs. Thank you

Yep. Here for Corona. I'm a neurologist. Haven't dealt with ventilator settings in over 2 decades.

My cat loves the doctor's voice, and though usually very active, is sleeping nearby.

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!!!

very informative, i am starting my IM residency and these lectures made a great difference to my knowledge , thanks

I have no reason to know this this in depth. I never want to work in the ICU or anything. But what I don’t understand - I wish to figure out. And you made this very easy to understand. I really thrive off things being “dumbed down”and you did great

I really enjoy your videos, Roger. Thanks for sharing and making so many things easier to understand!

Thank you for sharing this educational resource! The creation of low-cost ventilators is incredibly crucial, now more than ever. Understanding how a ventilator works and why it is needed is a necessary step towards solving the global ventilator shortage.

Great explanation dr. Thanks

Thanks for the review! Just picked up a home vent patient. 🤙

Very helpful as I am currently rotating in ICU.Thanks

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 !🤗👏👏👏

I am here becoz of covid 19. Thank you doctor , immensely for the valuable video.

These are just brilliant. Excellent teacher, great level of detail. Thanks!

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.

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?

Your videos are always helping me a lot to understand every kind of topic....thank you very much....

Explained in a very simple comprehensible way to any beginner

Great video! I LOVE MedCram content! I've been making similar videos, inspired by you guys. Keep up the great work, MedCram!

wonderful.Simple and easy to understand.God Bless

as always your lectures makes the subjects easy to understand and of course to remember.

Who else is here because of Corona Virus?

Clear and simple introduction to mechanical ventilator dynamics. Well done.

Best video on KZfaq !!! Very informative

God bless science ❤️ this is saving my dads life right now recovering from covid on the path to a healthy recovery

doc..ur understanding of the science and the way u made me understand it.. is marvellous..bow down to u sir...

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, 3. I did light mouth taping at night in order to ensure nose breathing all night, 4. I do an 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.

Nice and simple; thank you so much for making a difference in our practice and hence, the lives of many grateful patients!

Another outstanding period of instruction.

Your way of explaining difficult things with simple words is really gorgeous .. I love it ..

Great presentation! Simple explanation of a serious situation

excellent presentation for beginners

Thank you for these excellent and informative videos.

A Consultant Psychiatrist in UK -here in preparation to help patients if needed by supporting them on ventilator

modes explained lucidly. thanks.

Thanks for the very clear, didactic presentation!

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

excellent presentation Doctor.

wow awesome explanation thanks a lot !!!!

wow it is very fantastic and i hvae got alot of knowledges from this lectur video

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?

Great teaching. Very simple to understand. Thank you.

Thank you, great introduction.

Excellent presentation.

I'm here to prep for my last nursing exam (for advanced med surg)

Thank you so mucho for this information. It was explained really good, and you made it seems easy to understand!

You guys are awesome! I'm so glad I found this channel! Cheers from Israel

High quality instruction :)

Thanks Dr for this video as it helped me face my fear (THE VENTILATOR). Transitioning from Neuroscience to ICU RN :)

Awesome explanation.Thanks a lot.

Strong work guys! Love you lectures. Trying to get through them all!

thanku sir....a lot of help...we ll remember u till life...

I’m about to step into Mechanical Ventilation for Respiratory Therapy. It’s a notorious class & aspect that gets people dropped from my program all the time. It’s a lil less scary at the moment

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!

As good and as simple as it gets!!

Thank you for the easy-down to basics demo!

Thanks, very nice explanaition. - Learning from Brazil !!

2024 still im using ur most understandable lectures😍😍😍ㄲㄲ

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.

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.

THIS IS SO INCREDIBLY HELPFUL!!! THANK YOU! also here bc of coronavirus :)

very nicely explained

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.

thanks i really don't understand it well till before i saw this video

Thank you very much for this wonderful illustration of such a complicated topic

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!

Great teaching

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?

Nice video. Thank you for the good explanation!

Great refresher course.
