High-quality CPR for children requires compressing at least 1/3 of the chest depth (about 2 inches or 5 cm).

For two-rescuer infant CPR, the correct compression-to-ventilation ratio is 15:2.

Rescue breathing is recommended for victims with a pulse but inadequate breathing.

AED pads should be placed at least 1 inch away from a pacemaker to ensure proper function.

For single-rescuer infant CPR, use two fingers just below the nipple line to perform compressions.

Reassessment should occur every 5 cycles of CPR (about 2 minutes) unless an AED prompts earlier evaluation.

For a single rescuer, the correct ratio is 30 compressions to 2 breaths.

Chest compressions keep oxygenated blood circulating to the brain and heart until normal function is restored.

AED pads should be placed at least 1 inch away from a pacemaker to avoid interference.

The correct compression depth for adult CPR is at least 2 inches (5 cm).

Equal chest rise and fall confirms proper ventilation and airway placement.

A firm surface is needed to ensure effective compressions.

For two-rescuer pediatric CPR, the correct compression-to-ventilation ratio is 15:2.

In a hospital setting, bag-mask ventilation is the preferred method for delivering rescue breaths.

Unlike adults, the most common cause of cardiac arrest in infants and children is respiratory failure leading to hypoxia.

The two-thumb encircling hands technique is the preferred method for two-rescuer infant CPR, as it provides better depth and control.

The recommended compression rate is 100-120 compressions per minute.

Switching roles every 2 minutes minimizes interruptions and maintains high-quality CPR.

Pulse checks should be limited to 10 seconds to avoid delaying CPR.

Switching roles every 2 minutes prevents rescuer fatigue and minimizes interruptions.

Excessive ventilation can cause complications like gastric inflation.

If a choking victim becomes unresponsive and pulseless, CPR should begin immediately, starting with compressions.

Excessive ventilation can cause complications like gastric inflation.

The carotid artery is the preferred site for pulse assessment in unresponsive adults.

Most AEDs are programmed to reanalyze the heart rhythm every 2 minutes.

Pediatric AED pads should be used for children under 8 years old, if available.

High-quality CPR requires minimizing interruptions to maintain circulation.

Switching roles every 2 minutes ensures high-quality compressions without fatigue.

Agonal breathing is a sign of cardiac arrest and CPR should be initiated.

Equal chest rise confirms proper ventilation and airway placement.

For children, compress the chest at least 1/3 of its diameter (about 2 inches or 5 cm).

Encourage the victim to keep coughing instead of immediately intervening.

For adults with an advanced airway, ventilation should be given at a rate of 1 breath every 6 seconds.

Rescue breathing is recommended for victims with a pulse but inadequate breathing.

Gasping (agonal breathing) is not normal breathing and should not delay CPR.

CPR should continue until the patient shows signs of life, an AED prompts a shock or no shock, or another trained provider takes over.

Effective compressions allow full chest recoil, ensuring proper circulation.

For a responsive choking adult, abdominal thrusts (Heimlich maneuver) should be used.

Defibrillation should be performed as soon as a shockable rhythm is detected by the AED.

Rescue breaths should be given before starting chest compressions in drowning victims.

For infants, responsiveness is assessed by tapping the bottom of the foot and shouting.

Visible chest rise confirms that breaths are being delivered effectively.

Before starting CPR, check for a pulse for no more than 10 seconds to determine if compressions are needed.

Agonal breathing is a sign of cardiac arrest and CPR should be initiated.

Switching roles every 2 minutes prevents rescuer fatigue and ensures continuous, high-quality CPR.

Infant chest compressions should be at least 1/3 of the chest depth, approximately 1.5 inches (4 cm).

High-quality CPR requires minimizing interruptions to maintain circulation.

To minimize interruptions in care, breathing and pulse checks should be performed simultaneously, taking no more than 10 seconds.

High-quality chest compressions are the top priority in cardiac arrest, with ventilation as a secondary focus.

If the patient has a pulse but is not breathing, rescue breathing should be provided with continuous monitoring.

Excessive ventilation can cause complications like gastric inflation.

Rescue breathing is recommended for victims with a pulse but inadequate breathing.

If the AED does not advise a shock, rescuers should immediately resume CPR.

Early defibrillation is the most critical step in increasing survival rates for patients in cardiac arrest with a shockable rhythm.

The first step after turning on an AED is attaching the electrode pads.
