Explanation
Q:1What is the recommended compression depth for a child (age 1 to puberty)?
Child compressions should be about one-third the depth of the chest, which is approximately 2 inches (5 cm). This ensures effective blood flow during CPR.
Q:2What is the correct compression depth range for an adult?
Adult chest compressions must be performed at a depth of 2 inches (5 cm) to no more than 2.4 inches (6 cm). Shallow compressions are ineffective.
Q:3In infants, which is the recommended location for a pulse check?
The brachial artery, located on the inside of the infant's upper arm, is the easiest and most reliable site for checking a pulse in a non-responsive baby.
Q:4Which compression technique is appropriate for a single rescuer performing CPR on an infant?
The two-finger technique is the standard method for a single rescuer administering chest compressions to an infant to achieve the correct depth and rate.
Q:5To maximize the effectiveness of defibrillation, compressions should be resumed immediately after the shock and the pause should be less than:
Minimizing the time between the last compression and the shock, and immediately resuming compressions afterward, is critical. The pause should be less than 10 seconds.
Q:6If a pulse check is inconclusive after 10 seconds, what is the immediate next step?
If you cannot definitively feel a pulse within 10 seconds, assume cardiac arrest and initiate chest compressions immediately. Do not delay life support.
Q:7In general, at what approximate age or weight are adult AED pads appropriate for use?
Adult pads are used for patients 8 years and older, or those weighing more than 55 pounds (25 kg). Child pads should be used otherwise, if available.
Q:8What is the most reliable indicator that effective rescue breaths are being delivered during mouth-to-mouth ventilation?
Visible, gentle chest rise is the primary indicator of an effective rescue breath. Avoid forceful breaths that can cause stomach distension (gastric inflation).
Q:9Once cardiac arrest is recognized (unresponsive, not breathing, no pulse), chest compressions must be initiated within how many seconds?
High-quality CPR must be initiated within 10 seconds of recognizing cardiac arrest to maximize the patient's chance of survival.
Q:10Why is Ventilation not explicitly listed as a separate link in the Adult Chain of Survival?
For adults with sudden cardiac arrest, the emphasis is on immediate, high-quality compressions (C) and defibrillation (D) to circulate blood. Ventilation is included in CPR.
