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

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

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

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

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

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

The correct compression depth for adult CPR is at least 2 inches (5 cm).

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

Excessive ventilation can cause complications like gastric inflation.

For infants, responsiveness is assessed by tapping the bottom of the foot and shouting.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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.

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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

Naloxone should only be administered if opioid overdose is suspected.

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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.

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

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