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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

In BLS, medication administration is not a designated role—this falls under ACLS-level care.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

AED pads should be placed at least 1 inch away from a pacemaker to avoid interference.

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.

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

Naloxone should only be administered if opioid overdose is suspected.

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

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

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

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

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

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

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

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

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

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

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

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

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

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