Oxygenation -Understanding your BVM Device 2

Understanding the mechanics of oxygen delivery using BVM requires an appreciation of its component valves. The first BVM Device has 5 valves, 3 at the rear and 2 in the front. The forward duckbill valve is a one way valve allowing flow to the patient. A second expiratory disc valve is what differentiates this set up from others. It is a one way valve sitting below the duckbill allowing expired gas to exit while preventing room air entrainment. In contrast the second BVM (a 4 valve device) has a single forward duckbill valve with an expiratory port below it on the side the distal elbow connector. This port allows bidirectional flow. If the patients minute ventilation exceeds the flow to the mask air will be entrained and dilute delivered oxygen (FDO2). This can be managed by placing a PEEP valve over this port which creates a one way exit for expired gas (and allows for the application of PEEP). All of this applies to passively oxygenating the spontaneously breathing patient ie. not squeezing the bag.

Thank you so much , very nice video

[@christinagomez1334]

Hi great video, What is the difference between using a corrugated tubing reservoir, and an 02 bag reservoir ?

[@mikebushey916]

If you had an apneic patient and a tight seal with the BVM, will the patient receive any passive oxygen through the duck bill valve if you weren't assisting respirations?

[@lucasmcakennam2502]

My understanding is no, they would not revive any oxygen. you have to squeeze the bag reservoir to force the “duck bill” open and deliver the oxygen, with the expired C02 leaving through the valve passively.

I’m a smoker and a paraplegic, I’m paranoid about getting this virus. I’m thinking about ordering one of these on Amazon in case I get sick. Do I need an oxygen tank or something ? Please help.

[@philipbrennan4045]

Having oxygen will create a better system, but it is not necessary. By squeezing the bag without pure oxygen in the system you will still increase your lung volume, but you will need a peep valve as he shows here.

[@positronisomer206]

@@philipbrennan4045 no way. If you are so sick you need supplementary oxygen please call 911. ER doc here. don't try to self treat with a BVM at home, that's lunacy.

Richard Byrne but if my husband can’t get into ER and treated fast enough isn’t ambu bag better than nothing? I’m worried about people not being able to get Off ventilators

I like ambubags

Bonjour, je voulais savoir si vous pouvez me faire essayer.

Dont know if you guys gives a shit but if you're stoned like me atm you can watch all of the latest movies and series on instaflixxer. I've been streaming with my brother lately xD

[@brysontoby3706]

@Yusuf Nash definitely, I have been watching on instaflixxer for since november myself :D

[@kylerobinson8913]

Will someone please confirm or dismiss the rumor that less than 20 percent of people that need mechanical ventilation live?
I have heard it was a 15-20% survival rate after ventilators.

[@Harlem55]

These make killer pot pipes if you modify the end of the bag to accept a bowl.
