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

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

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

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

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

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

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

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

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

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

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

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

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

Pulse checks should be performed approximately every 2 minutes when providing rescue breathing.

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

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

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

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

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

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.

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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.

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

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

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

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

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

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

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

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

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

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

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

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

Equal chest rise confirms proper ventilation and airway placement.

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

Equal chest rise and fall confirms proper ventilation and airway placement.

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

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

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

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

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

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

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

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

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

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

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