OFA CPR Techniques & Automated External Defibrillation (AED)

Question 1

What is the correct compression rate for adult CPR?

Accepted Answer

100-120 compressions per minute

Answer

The recommended compression rate for adult CPR is 100 to 120 compressions per minute. This rate ensures that blood is circulated effectively throughout the body, providing vital oxygen to the brain and other organs, which is crucial for survival during cardiac arrest.

Question 2

Where should you place your hands during chest compressions on an adult?

Accepted Answer

On the center of the chest between the nipples

Answer

For effective chest compressions on an adult, hands should be placed on the lower half of the sternum (breastbone), specifically in the center of the chest between the nipples. This position ensures that compressions are delivered directly over the heart, maximizing blood flow with each compression.

Question 3

When should an AED be used during a cardiac emergency?

Accepted Answer

As soon as it's available

Answer

An Automated External Defibrillator (AED) should be used as soon as it becomes available during a cardiac emergency. Early defibrillation is critical for victims of sudden cardiac arrest caused by ventricular fibrillation, as it can stop the irregular heart rhythm and allow the heart to resume a normal beat, significantly increasing survival rates.

Question 4

What is the purpose of rescue breaths during CPR?

Accepted Answer

To deliver oxygen to the victim

Answer

Rescue breaths during CPR are designed to deliver oxygen to the victim's lungs, which then gets circulated to the brain and other vital organs by the chest compressions. This oxygen delivery is crucial to prevent brain damage and support organ function while waiting for advanced medical care.

Question 5

What should you do after the AED delivers a shock?

Accepted Answer

Resume CPR immediately

Answer

After an AED delivers a shock, it is crucial to immediately resume chest compressions and continue CPR without delay. The shock may temporarily stop the abnormal heart rhythm, but continuous compressions are needed to help the heart regain its normal function and circulate oxygenated blood throughout the body.
