YMCA Lifeguard CPR, AED & First Aid for the Professional Rescuer

Question 1

What is the correct compression-to-breath ratio for single-rescuer adult CPR?

Accepted Answer

30:2

Answer

For single-rescuer adult CPR, the correct compression-to-breath ratio is 30 compressions followed by 2 rescue breaths. This ratio is recommended by major resuscitation guidelines to ensure an adequate balance of chest compressions, which circulate blood, and ventilations, which provide oxygen. Maintaining this ratio is crucial for effective resuscitation efforts.

Question 2

Which step should you take immediately after attaching AED pads to a victim?

Accepted Answer

Analyze the victim’s heart rhythm

Answer

Immediately after attaching AED pads to a victim, the next crucial step is to allow the AED to analyze the victim’s heart rhythm. The AED will then determine if a shockable rhythm is present and advise whether a shock is needed. It is important not to touch the victim during this analysis phase to ensure accurate readings and prevent injury.

Question 3

How deep should chest compressions be for an adult during CPR?

Accepted Answer

At least 2 inches

Answer

For an adult during CPR, chest compressions should be at least 2 inches deep, but no more than 2.4 inches. This specific depth is crucial to effectively circulate blood to vital organs like the brain and heart. Compressing too shallowly is ineffective, while compressing too deeply can increase the risk of injury.

Question 4

What should you do if a conscious choking adult cannot speak or cough?

Accepted Answer

Begin abdominal thrusts

Answer

If a conscious choking adult cannot speak or cough, it indicates a severe airway obstruction requiring immediate intervention. In this situation, abdominal thrusts (the Heimlich maneuver) are the recommended first aid. These thrusts create an artificial cough to dislodge the foreign object from the airway, restoring the ability to breathe.

Question 5

Why is early defibrillation important during a cardiac arrest?

Accepted Answer

It increases survival rates

Answer

Early defibrillation is paramount during a cardiac arrest, especially when caused by ventricular fibrillation, because it delivers an electrical shock to reset the heart's rhythm. This immediate intervention can stop the chaotic electrical activity and allow the heart to resume a normal, effective beat. The sooner defibrillation occurs, the higher the chance of survival for the victim.
