High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Visible chest rise confirms that breaths are being delivered effectively.

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

Over-ventilation can lead to increased intrathoracic pressure, reducing venous return and cardiac output.

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

The best way to ensure effective ventilation is by observing visible chest rise with each breath.

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

Visible chest rise is the best indicator that rescue breaths are effectively ventilating the lungs.

Equal chest rise confirms proper ventilation and airway placement.

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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