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

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

Naloxone should only be administered if opioid overdose is suspected.

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

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

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

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

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

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

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

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Breaths should be delivered over 1 second each to produce visible chest rise.

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

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

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

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

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

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

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

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.

CPR should continue until the patient shows signs of life, an AED prompts a shock or no shock, or another trained provider takes over.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

A firm surface is needed to ensure effective compressions.

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

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

Encourage the victim to keep coughing instead of immediately intervening.

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

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

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

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

The E-C clamp technique ensures a tight seal while lifting the jaw for an open airway.

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

Excessive ventilation can cause complications like gastric inflation.

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

Visible chest rise confirms that breaths are being delivered effectively.
