wat is the volume of air given during 1 breath while performing cpr?

Answer 1

True it should be enough to make the chest rise and fall. The aprox amount in an adults lungs is between 4 litters and 6 liters. That's how much a normal adult has in their lungs to blow out.

The average adult ambu bag used for "bagging" the patient holds 800 ml of air volume.

Note; normal tidal volume (5-7 ml pr kg) is a resting breath in or out. That is not enough to inflate someones lungs. You would need more volume and pressure to overcome the pressure in the unconscious persons lungs. Also known as positive pressure artificial breathing.

Answer 2

That depends on the rescuer and the total tidal volume of their lungs. Obviously, someone with lung problems is not going to deliver the same volume as an aerobics instructor.

Rhe answer would be, "somewhat less than the total tidal volume of the rescuer!"

If you have taken a recent CPR course you will note that they are now de-emphasizing rescue breathing over total number of compressions. There are more compressions and fewer breaths. Circulation is more important than oxygenation.

Answer 3

No one measures it during care. You just give enough to cause the chest to gently rise without over-inflating. The volume will depend on a lot of factors.

Answer 4

Google it for more information on cpr but personally i think it would differ from person to person depending on their lung capacity and other different attributes

Answer 5

I don't know the exact amount but on any size person child or infant. it needs to be enough to make the chest rise and fall
