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

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

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

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

Once an advanced airway is in place, continuous compressions are given with 1 breath every 6 seconds.

Encourage the victim to keep coughing instead of immediately intervening.

Reassessment should occur every 5 cycles of CPR (about 2 minutes) unless an AED prompts earlier evaluation.

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

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

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

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

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

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

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

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

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.

A firm surface is needed to ensure effective compressions.

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

To minimize interruptions in care, breathing and pulse checks should be performed simultaneously, taking no more than 10 seconds.

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

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

High-quality CPR for children requires compressing at least 1/3 of the chest depth (about 2 inches or 5 cm).

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.

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

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

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

Switching roles every 2 minutes minimizes interruptions and maintains high-quality CPR.

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

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

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

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

Rescue breathing should be initiated for a patient with a pulse but no normal breathing.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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