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

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

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).

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

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

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

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

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

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

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

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

Equal chest rise confirms proper ventilation and airway placement.

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.

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

Naloxone should only be administered if opioid overdose is suspected.

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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).

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

High-quality chest compressions are the top priority in cardiac arrest, with ventilation as a secondary focus.

Clear role assignment and minimizing interruptions optimize CPR quality in a team setting.

For an unresponsive, pulseless patient, immediate chest compressions are the priority.

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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.

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

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

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

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

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

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

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 prevents rescuer fatigue and ensures continuous, high-quality CPR.

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