Review questions: CPR

371.  If multiple rescuers are present, how often should they rotate their tasks?

If multiple rescuers are available, they should rotate the task of compressions every 2 minutes.

372. What are two methods for opening the airway in an unresponsive victim who is not breathing?

The airway of an unresponsive victim can be opened using the head tilt– chin lift or jaw thrust followed by rescue breaths.

373.  After inserting an advance airway into the victim, how do the rescuers modify their CPR technique?

Once an advanced airway is in place, healthcare providers will deliver ventilations at a regular rate 1 breath every 6 seconds (10 breaths/minute) and chest compressions can be delivered without interruption.

374.  The victim’s chance of survival decreases with an increasing interval between the arrest and defibrillation.  True or False

True. Thus early defibrillation remains the cornerstone therapy for ventricular fibrillation and pulseless ventricular tachycardia.

375.  What is one of the most important factors for successful defibrillation for a victim of cardiac arrest?

One of the most important determinants for successful defibrillation is the effectiveness of chest compressions. Defibrillation outcome is improved if interruptions (for rhythm assessment, defibrillation, or advanced care) in chest compressions are kept to a minimum.
