How do you think you can measure the FiO2 delivered to an intubated patient? Is it possible using a flow sensor in the oxygen intake and compare it with the flow delivered to the patient? Are there other options?
Great video. But could you please explain, in the valve assembly is the upper valve known as the inspiratory valve and the lower valve the expiratory valve?
Great video. One point which wasn't clear was how the oxygen gets into the optional reservoir via a port which seemed to have a valve against it when it was pressure tested...?
Good point about anchoring and supporting the flow meter while connecting the tubing. Don't think we have been doing that, might be a good point to bring up in class again.
Nice one. Can this inexpensive bvm be adapted to have a mechanical reliable “squeezer” to help alleviate the current shortage of ventilators due to covid 19?
Upon setting up and using a duckbill valve FMV, I notice the duckbill valve staying open while the flow meter is set to flush. Why is this? Is the valve old?
When you use high flows greater than 15 LPM (FLUSH), the flows may be too high causing unintentional PEEP as the system can't vent the excessive gas coming into the BVM system. Try turning down the flow till you have just enough flow coming into the system to keep the optional reservoir inflated while bagging the patient (note that it doesn't need to be over distended). That should still deliver near ,maximal FiO2 and minimize PEEP as the duckbill should close properly.
As long as your using it correctly it will supply "gas" to a patient. The oxygen level (FiO2) and length the tank or source will last depends on the speed of the gas flow into your bagger and how many times per minute you squeeze the bag. The faster the gas flow rate and respiratory rate, the less time your gas cylinder will last.
Hi George, I'm from TTSH singapore and would like to seek permission for usage of your youtube videos for our elearn. We would like to post the link to your youtube videos in our elearn for education purpose. please advise. Thanks!
I am a seafarer and I found this video extremely helpful. Thanks for your efforts sir.
Hi George! I teach an EMR class and my kids absolutely adore your videos and so do I! We love you! Keep up the great work
I'm one of the students love you George!
"When You're attaching the... Ouch!" That was a classic! You are such a great RT!!!
So glad I found your channel. Because of you “I get it” and I’m not scared on the job if I keep watching your training.
Thanks for being so thorough and easy to understand.
Anchoring the flow meter was a really practical advice!
Great explanation Mr. George

thank you for this detailed demonstration!
Ooo...u always make my concept clear..thank you so much..♥️♥️
Great video. But could you please explain, in the valve assembly is the upper valve known as the inspiratory valve and the lower valve the expiratory valve?
then which one is the fish mouth valve?
Great video. One point which wasn't clear was how the oxygen gets into the optional reservoir via a port which seemed to have a valve against it when it was pressure tested...?
So the mail resuscitate a has a Weather RAW all about Piper has one as well, so they kind of the same
very well explanation, thank you sir.
Thanks very much. I appreciate your comment.
Good point about anchoring and supporting the flow meter while connecting the tubing. Don't think we have been doing that, might be a good point to bring up in class again.
Can you clarify how much is not too much and not too little o2 ?if that makes sense....
Hi, what's the name of the reservoir to ambu valve? I can't find where to buy it in internet.
Thanks, excelente video
You can google it up
Oxygen Reservoir Bag...
Nice one. Can this inexpensive bvm be adapted to have a mechanical reliable “squeezer” to help alleviate the current shortage of ventilators due to covid 19?
Yeah, you can. It will be a mechanical BVM/bagger, not a proper ventilator. Useful enough
Henry Salomon I will make a mechanical squeezer. Should the squeezer squeeze all the air out of the bag in “one burst” or do it gradually ?
Squeezers will probably be the recovered immune.
Very educative thank you
Thank you so much good information
Is some kind on venturi valve not required to restrict the percentage of oxygen flowing into the unit?
No. These are used during resuscitation where you will want an FiO2 of as close to 1 as possible.

@@GeorgeORRT Thank you; I am a second-year RT student
@@lukemoran6557 No problem. Hope that your studies are going well!
@@GeorgeORRT Is there any way you could do a video where you demonstrate all the different breathing patterns: Biots, Cheyne-Stokes, Kussmaul...etc???
Very good teacher
Anything in particular?
Thanks
Sir how much time it will give oxygen to patients
Pls reply sir

Where us the exhalation port
Very informative!
Thanks, Glad it was helpful. Have a good day
Hi pls make a video on mechanical ventilator basics...
thanks for ur videos
❤
Thanx
Your welcome
What is the capacity of the bag (ltr per squeeze). Can u pl share a reliable source which can be purchased in India
Nice sir
Thank you for your comment

Hi Jimmy: That's fine, go ahead and link them. George
Unfortunately one doesn't have time to do all that during a code :D
