Cheers for this, I have been researching "how do i stop my cpap mask from leaking?" for a while now, and I think this has helped. Have you heard people talk about - Panvaryor Unexpected Preference - (should be on google have a look ) ? It is a great one off guide for discovering how to eradicating sleep apnea and snoring without the hard work. Ive heard some awesome things about it and my brother in law got excellent results with it.
It was a knowledge full video l found it helpful in understanding ventilation modes ,plz carry on
My goodness, this is the best explanation I've ever seen. Thank you. Consider me subscribed!
PEEP is not usually measures in mmHg, it is also measured in cmH2O
Thank you Dr. Seheult, love your lectures
You're welcome!
Excellent video. These are useful for docs that do not normally run ventilators, but may be called to do so, with the COVID pandemic
Essential info. best explained for non resp. med staff, operating ventilators during Pandemic .Thank you
Beautiful
My husband is watching this. Can I modify a BiPAP machine to act as a ventilator for COVID 19 surge
Great👍👍
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)?
That was my question as well. Because the PEEP is already set at 5, the alveoli should maintain a pressure of 5 consistently.
@@kevingreen3421 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.
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
Why pressure will increase in lung by increase volume delivered to lung..u said both are inversely proportional🤔? Video around..9:40
Will you consider labeling these videos as a series? I appreciate the information, but I did not know this was a continuation of another video until I began watching. Now I have to go find the earlier video. A link would make this easier.
These videos are always so concise thank you
The CORONA VIRUS brought me here- March 29, 2020
I love to put these on as podcast during driving 👍😉
be careful
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.
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
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.
Would you ever consider doing any case study walk-throughs? I get so much out of your lectures and would love to see it applied to scenarios. THANK YOU FOR ALL YOU DO!!
Please refer to your RT ! 🥰
Wow.. Thanks
Are PEEP units in standard atmospheres pressure?
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.
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?
Amazing video. Thanks to Corona Virus, your videos are coming to fore! Keep up the good work, Doc!
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 :) !
Hi. What is the most difficult aspect of ventilator construction?
Excellent Video. Being an engineering student with no background in field of medicine, it was really easy to understand.
Made it very simple and comprehensible in one go..... Thanq so much.
audio quality is terrible. constant background echo
Fantastic lecture/video! RRT out
Thanks, we're big fans of RRTs! Have you checked out our lung ultrasound course yet? 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.
@@Medcram Yes i have and it is just as good as this one! This is my favorite medical YT channel
thankyou a better explanation than that which I used to build DIY ventilator, very interesting.Shame I didnt see this 2 months ago lol
thanks .. but is the peep measured in cmH2O or mmHg
Bit late, buddy but its cmH2O
Excellent
Perfect video!
Perfect am grateful and I benefit from your lectures. Keep the spirit
How do I put that I love this videos? I can't! and I just love them! Amazing thanks!!!
Great Explanation. I understood the concepts quite easy. Sir You are awesome teacher.
And here I am using my own lungs like a sucker. - Homer Simpson
I learned more from these videos than from my professors.
I have a question...can you please explain why we see apnea ventilation alarm on the ventilator while it's on SIMV mode ? Isn't the ventilator supposed to deliver mandatory preset rate of breaths to the patient?
this is awesome, simple and elegant. many big thanks!
Great video. Keep making more lectures!
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
Thankyou sir.
Hi. What is the most difficult aspect of ventilator construction?
Reliability
Excellent !
Whats the difference btween ipap and pressure support????????????
Thank you so much. You’re such a blessing 😊
Thank you so much
You're welcome.
why does the flow go below zero?
Breathing out
what's the video following this
Excellent. Thanks indeed
Wonderful 😊
Beautifully explained!!
very good video!
Thank you Sir!
Why start at 5 ? Ps ? You mean PSV? Is not NOT like AC! This is maybe good for an explanation for a resident, but it's not exact. Maybe you should have had a Respiratory Therapist do the education?
Thank you. 😭
Thanks 👍
I've been working as a respiratory physiotherapist during this covid period and trying my best to understand ventilators and this video is a God-send!
Thank you, and much appreciation from South Africa 🇿🇦
thanks for sharing
