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

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

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

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

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

If the patient has a pulse but is not breathing, rescue breathing should be provided with continuous monitoring.

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

Over-ventilation can increase intrathoracic pressure, reducing venous return and cardiac output.

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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).

High-quality CPR requires minimizing interruptions to maintain circulation.

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

Shifting the uterus to the left reduces pressure on the inferior vena cava, improving circulation.

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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.

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

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

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

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

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

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.

A firm surface is needed to ensure effective compressions.

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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