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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

If a choking victim becomes unresponsive, emergency services should be activated, and CPR should begin immediately.

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

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

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

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

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

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

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

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

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

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

Switching roles every 2 minutes prevents rescuer fatigue and ensures continuous, high-quality CPR.

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

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

The first step is to turn on the AED before attaching pads and following voice prompts.

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

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.

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

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

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.

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

Equal chest rise confirms proper ventilation and airway placement.

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

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

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

A firm surface is needed to ensure effective compressions.

High-quality CPR requires minimizing interruptions to maintain circulation.

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).

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.

For infants, the correct pulse check location is the brachial artery (inside the upper arm).

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

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

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

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

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

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

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

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

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

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

Reassessment should occur every 5 cycles of CPR (about 2 minutes) unless an AED prompts earlier evaluation.

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

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

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