2. what is the main goal of performing chest compressions during cpr?

a. keep blood flowing or circulating to the brain and heart
b. help the person breath
c. keep compressions at 30:1
d. compressions are not needed in cpr

1. after a person collapses, how many minutes of oxygen are left in the blood?

a. 8 - 10 minutes
b. 5 - 10 seconds
c. 8 - 10 seconds
d. 12 - 20 minutes

Explanation:

• 71. In case of cardiac arrest with gasping (not normal breathing), start CPR immediately. So the answer is B.
• 72. Ventricular Fibrillation is a common cause of cardiac arrest. Cough, diabetes and fever are not typical direct causes. So the answer is D.
• 73. High - quality CPR is required for a victim with no normal breathing and no pulse. So the answer is B.
• 74. Trauma, blood loss and electrocution can all cause cardiac arrest. So the answer is D.
• 75. To ensure effective breaths with a BVM, observe the chest rise with each breath. So the answer is A.
• 76. At the 4 - minute mark without oxygen, brain cells start to die.
• 77. The main goal of chest compressions in CPR is to keep blood flowing or circulating to the brain and heart. So the answer is A.
• 78. After a person collapses, there are about 8 - 10 seconds of oxygen left in the blood. So the answer is C.

4. D. All of The Above
5. A. Observing the chest rises with each breath
6. Brain cells start to die
