If there is any doubt about the presence of a pulse, start chest compressions immediately.

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

Visible chest rise confirms that breaths are being delivered effectively.

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

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

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

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

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

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

Excessive ventilation can cause complications like gastric inflation.

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

A firm surface is needed to ensure effective compressions.

A firm surface is needed to ensure effective compressions.

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

For infants, the correct pulse check location is the brachial artery (inside the upper arm).

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

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

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

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

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

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

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

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

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

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

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