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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Visible chest rise confirms that breaths are being delivered effectively.

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

Early defibrillation is the most critical step in increasing survival rates for patients in cardiac arrest with a shockable rhythm.

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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

Excessive ventilation can cause complications like gastric inflation.

Excessive ventilation can cause complications like gastric inflation.

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

A firm surface is needed to ensure effective compressions.

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

Chest compressions should continue while the AED is charging to maintain circulation.

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

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

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

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

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.

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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