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

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

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

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

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

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

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

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

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

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

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

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

If a patient is unresponsive with a suspected airway obstruction, chest compressions should be initiated immediately to help clear the airway.

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

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

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

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

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

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

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

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

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

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

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

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

If a patient has a pulse but is not breathing adequately, healthcare providers should provide rescue breathing without chest compressions.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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.

Switching roles every 2 minutes prevents rescuer fatigue and minimizes interruptions.

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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