Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

Naloxone should only be administered if opioid overdose is suspected.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

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

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

If a choking victim becomes unresponsive and pulseless, CPR should begin immediately, starting with compressions.

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

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

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

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

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

High-quality CPR for adults requires compressions at least 2 inches deep at a rate of 100-120 per minute.

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

Closed-loop communication ensures that orders are acknowledged and carried out correctly.

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

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

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

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

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

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

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

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

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

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

The two-thumb encircling hands technique is the preferred method for two-rescuer infant CPR, as it provides better depth and control.

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

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

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

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

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

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

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

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

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

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

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