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

For two-rescuer infant CPR, the correct ratio is 15:2, not 30:2.

If a patient is unresponsive with a suspected airway obstruction, chest compressions should be initiated immediately to help clear the airway.

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

Equal chest rise confirms proper ventilation and airway placement.

A firm surface is needed to ensure effective compressions.

Rescuers should switch every 2 minutes (or 5 cycles of compressions) to maintain high-quality CPR.

High-quality CPR requires minimizing interruptions to maintain circulation.

The first step is to turn on the AED before attaching pads and following voice prompts.

An AED is used on patients who are unresponsive, pulseless, and not breathing.

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

A firm surface is needed to ensure effective compressions.

Excessive ventilation can cause complications like gastric inflation.

Ventilations should be given every 6 seconds when an advanced airway is in place.

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

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

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

Adult chest compressions should be at least 2 inches (5 cm) deep.

Chest compressions maintain circulation and deliver oxygenated blood to the brain and heart.

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

For adults with a pulse but not breathing, provide 1 breath every 5-6 seconds.

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

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

Encourage the victim to keep coughing instead of immediately intervening.

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

If there is any doubt about the presence of a pulse, start chest compressions immediately.

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

Excessive ventilation can cause complications like gastric inflation.

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

For a choking infant, back slaps and chest thrusts should be used instead of abdominal thrusts.

Naloxone should only be administered if opioid overdose is suspected.

For children with a pulse but no normal breathing, provide rescue breaths at a rate of 12-20 per minute.

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

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

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

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

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

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

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

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

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

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

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

Closed-loop communication ensures that orders are acknowledged and carried out correctly.

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

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

When a shockable rhythm is detected, defibrillation should be performed as soon as possible.

Adult chest compressions should be at least 2 inches (5 cm) deep.
