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

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

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

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

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

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

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

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

For adults with an advanced airway, ventilation should be given at a rate of 1 breath every 6 seconds.

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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 best way to ensure effective ventilation is by observing visible chest rise with each breath.

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

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

Shifting the uterus to the left reduces pressure on the inferior vena cava, improving circulation.

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

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

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

A firm surface is needed to ensure effective compressions.

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

Equal chest rise confirms proper ventilation and airway placement.

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

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

Encourage the victim to keep coughing instead of immediately intervening.

Clear role assignment and minimizing interruptions optimize CPR quality in a team setting.

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

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

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

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

If a choking victim becomes unresponsive and pulseless, CPR should begin immediately, starting with compressions.

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

Excessive ventilation can cause complications like gastric inflation.

Breaths should be delivered over 1 second each to produce visible chest rise.

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

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

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

Naloxone should only be administered if opioid overdose is suspected.

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

Rescue breathing should be initiated for a patient with a pulse but no normal breathing.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

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

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