High-quality CPR requires minimizing interruptions to maintain circulation.

Visible chest rise confirms that breaths are being delivered effectively.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

Excessive ventilation can cause complications like gastric inflation.

Each breath should be given over 1 second with just enough volume to see the chest rise.

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

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

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

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

Over-ventilation can increase intrathoracic pressure, reducing venous return and cardiac output.

A firm surface is needed to ensure effective compressions.

For suspected spinal injury, the jaw thrust maneuver should be used instead of head tilt-chin lift.

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

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

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.

Encourage the victim to keep coughing instead of immediately intervening.

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

Equal chest rise confirms proper ventilation and airway placement.

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

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

Naloxone should only be administered if opioid overdose is suspected.
