Question

PLEASE HELP ME


If CPR is not performed, how many minutes will elapse before the brain becomes damaged from lack of oxygen?
(Points : 1)
1
2
4
10

Answer 1

1- brain cells begin to die. 3- serious brain damage likely. 10- many brain cells have died and the person is unlikely to recover.

Answer 2

I'd say 4. (I had this question in class before.)

Answer 3

CPR can be lifesaving, but it is best performed by those who have been trained in an accredited CPR course. The procedures described here are not a substitute for CPR training. The newest techniques emphasize compression over rescue breathing and airway, reversing long-standing practice.

Time is very important when an unconscious person is not breathing. Permanent brain damage begins after only 4 minutes without oxygen, and death can occur as soon as 4 - 6 minutes later.

When someone starts CPR before emergency support arrives, the patient has a much greater chance of surviving. Yet, when most emergency workers arrive at a cardiac arrest, they usually find no one giving CPR.
