The bag-mask device is not recommended for a single rescuer to provide breaths during CPR.
a device NOT recommended is a oxygen tank or a heart jump starter i actually haft to know this because I'm a 2nt class in boy scouts and i did that 4 the tenderfoot rank.
A bag valve mask (BVM) is not recommended for a single rescuer to provide breaths during CPR.
Bag-mask device
I assume this is a test question. Shame, shame. :) Unless the rescuer is trained with proper equipment, simply provide compressions. Do not stop for breaths as it is more effective without them.
A 100 ton metal press.
It is called a BVM or bag valve mask that is not recommended for single person use.
Use a barrier device when giving rescue breaths to any victim in order to...A) prevent air from escaping the victim's lungsB) help regulate the amount of air you blowC) prevent victim from vomitingD) prevent transmission of infections
30 compressions 2 breaths. Per 2010 AHA guidelines. Compression only CPR can be performed if no barrier device is present.
1 rescuer CPR for infant is 30 compressions to 1 breath.
CPR involves chest compressions at least 5 cm deep and at a rate of at least 100 per minute in an effort to create artificial circulation by manually pumping blood through the heart. In addition, the rescuer may provide breaths by either exhaling into the subject's mouth or utilizing a device that pushes air into the subject's lungs.
A case made by the manufacturer of your device will provide the best fit.
make sure it is around the mouth right to do the breaths
It could help spread the weight of the rescuer, give a easy to grip device for the rescued, and if shoved downward could even provide a way to climb out of the water.
prevent victim from vomiting
Give breaths at a rate of 1 breath every 3 to 5 seconds.
