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

Visible chest rise confirms that breaths are being delivered effectively.

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

A firm surface is needed to ensure effective compressions.

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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.

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

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

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

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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

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

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

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

AED pads should be placed at least 1 inch away from a pacemaker to avoid interference.

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

An AED analyzes the heart rhythm and delivers a shock if a shockable rhythm is present.

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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

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

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

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.

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

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

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

A firm surface is needed to ensure effective compressions.

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.

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

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