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

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

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.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

Naloxone should only be administered if opioid overdose is suspected.

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

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

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

Unless a valid DNR order is confirmed, resuscitation efforts should begin.

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

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

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

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.

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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.

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

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

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

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

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