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

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

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

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

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

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

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

For adults with a pulse but not breathing, provide 1 breath every 5-6 seconds.

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

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

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

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

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

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

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

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

Unless a valid DNR order is confirmed, resuscitation efforts should begin.

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

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.

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

After a shock is delivered, chest compressions should resume immediately to maintain circulation.

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

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

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.

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

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

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.

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

A firm surface is needed to ensure effective compressions.

Excessive ventilation can cause complications like gastric inflation.

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

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

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

Visible chest rise confirms that breaths are being delivered effectively.
