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

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

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

Single-rescuer infant CPR follows the 30:2 compression-to-ventilation ratio, just like adults.

Chest compressions should continue while the AED is charging to maintain circulation.

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

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

For suspected spinal injuries, the jaw thrust maneuver is used instead of head tilt-chin lift to maintain spinal alignment.

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

Breathing assessment should take no more than 10 seconds to avoid delaying CPR.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

Over-ventilation can lead to increased intrathoracic pressure, reducing venous return and cardiac output.

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

After a shock is delivered, chest compressions should resume immediately to maintain circulation.

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

A bag-mask device (BVM) is preferred for healthcare providers as it delivers more effective ventilations.

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

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

The E-C clamp technique ensures a tight seal while lifting the jaw for an open airway.

Once an advanced airway is in place, continuous compressions should be given at 100-120 per minute without pausing for breaths.

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

Visible chest rise confirms that breaths are being delivered effectively.

Naloxone should only be administered if opioid overdose is suspected.

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

High-quality chest compressions help circulate oxygenated blood to the brain and heart.

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

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

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

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