A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

Once an advanced airway is in place, continuous compressions are given with 1 breath every 6 seconds.

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

A firm surface is needed to ensure effective compressions.

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

Visible chest rise is the best indicator that rescue breaths are effectively ventilating the lungs.

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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

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

Equal chest rise confirms proper ventilation and airway placement.

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

Naloxone should only be administered if opioid overdose is suspected.

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

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

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

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

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

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

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

If a choking victim becomes unresponsive, emergency services should be activated, and CPR should begin immediately.
