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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

The first step is to turn on the AED before attaching pads and following voice prompts.

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

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

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

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

Reassessment should occur every 5 cycles of CPR (about 2 minutes) unless an AED prompts earlier evaluation.

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

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

Excessive ventilation can cause complications like gastric inflation.

When a shockable rhythm is detected, defibrillation should be performed as soon as possible.

A firm surface is needed to ensure effective compressions.

Naloxone should only be administered if opioid overdose is suspected.

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

The best method is to tap the patient and shout to assess for responsiveness.

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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.

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

Equal chest rise confirms proper ventilation and airway placement.

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

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

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