Chapter 9 Review

Signs of cardiac arrest include:

- Sudden collapse - unresponsiveness - Abnormal breathing - No pulse

Describe the five links in the Cardiac Chain of Survival for adults:

1. Call 911 or recognize emergency 2. Early CPR 3. Early defibrillation 4. Advanced life support 5. Integrated Post-Cardiac Arrest Care

Provide three examples why a lifeguard could or should stop CPR:

1. Obvious sign of life(normal breathing or movement) 2. AED is ready to analyze the victim's heart rhythm 3. Scene becomes unsafe

For each minute CPR and defibrillation are delayed the victims chance for survival is reduced by about ____ percent.

10

Compressions given at the correct rate are at least ____ per minute to a maximum of ____ per minute.

100, 120

What is the appropriate compression depth when providing CPR on an adult?

At least 2 inches but no more than 2.4 inches

When providing two-rescuer CPR, when should rescuers change positions?

At least every two minutes, After 5 cycles of 30 compressions and 2 ventilations, During the analysis of the AED

What is the objective of CPR?

CPR is given to circulate blood back into the body through effective chest compressions and ventilations.

When performing two-rescuer CPR on an infant, describe how lifeguards should modify the following:

Compression-to-ventilation ratio: 15 to 2 Compression technique: encircling thumbs technique

You arrive on the scene when another lifeguard is performing CPR, what should you do first?

Confirm that EMS is on the way. If not summoned, call EMS and then get AED. Get AED and help with 2 person CPR.

It is not appropriate to use an AED on a victim who is pregnant.

False; treat the same with CPR and AED. The fetus has the best chance of surviving when the mother does

What should you do if you think someone is having a heart attack?

Summon EMS personnel, have victim stop activity and rest in a comfortable position. Be prepared for CPR and use of AED.
