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

Agonal gasps are not normal breathing and should not delay CPR.

Pulse checks should be performed approximately every 2 minutes when providing rescue breathing.

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

The two-thumb encircling technique is preferred for two-rescuer infant CPR, while single rescuers typically use two fingers.

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

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

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

Rescue breathing is the correct response if the patient has a pulse but no breathing.

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

An AED analyzes the heart rhythm and delivers a shock if a shockable rhythm is present.

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

The best method is to tap the patient and shout to assess for responsiveness.

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

Equal chest rise confirms proper ventilation and airway placement.

For infants, the correct pulse check location is the brachial artery (inside the upper arm).

Naloxone should only be administered if opioid overdose is suspected.

For adult CPR, compressions should be performed with two hands, one on top of the other, placed on the lower half of the sternum.

Encourage the victim to keep coughing instead of immediately intervening.

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

A firm surface is needed to ensure effective compressions.

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

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

Encourage the victim to keep coughing instead of immediately intervening.

Excessive ventilation can cause complications like gastric inflation.

If a patient has a pulse but is not breathing adequately, healthcare providers should provide rescue breathing without chest compressions.

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

A firm surface is needed to ensure effective compressions.

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

Rescuers should switch every 2 minutes to maintain high-quality CPR and prevent fatigue.

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

For an unresponsive, pulseless patient, immediate chest compressions are the priority.

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

Rescue breathing is the correct response if the patient has a pulse but no breathing.

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

High-quality CPR for adults requires compressions at least 2 inches deep at a rate of 100-120 per minute.

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

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

Rescue breathing is the correct response if the patient has a pulse but no breathing.

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

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

If a choking victim can cough or speak, encourage them to keep coughing rather than immediately performing abdominal thrusts.

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

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.
