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

For adults with a pulse but not breathing, provide 1 breath every 5-6 seconds.

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

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

For suspected spinal injury, the jaw thrust maneuver should be used instead of head tilt-chin lift.

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

Defibrillation should be performed as soon as a shockable rhythm is detected by the AED.

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

For infants, responsiveness is assessed by tapping the bottom of the foot and shouting.

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

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

Naloxone should only be administered if opioid overdose is suspected.

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

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

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

High-quality CPR requires minimizing interruptions 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.

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

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

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

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

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

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

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

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

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

In a hospital setting, bag-mask ventilation is the preferred method for delivering rescue breaths.

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

Excessive ventilation can cause complications like gastric inflation.

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).

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

For suspected spinal injuries, the jaw thrust maneuver is used instead of head tilt-chin lift to maintain spinal alignment.
