Excessive ventilation can cause complications like gastric inflation.

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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).

A firm surface is needed to ensure effective compressions.

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

Unlike adults, the most common cause of cardiac arrest in infants and children is respiratory failure leading to hypoxia.

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 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.

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

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

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

Rescuers should switch every 2 minutes to maintain high-quality CPR and prevent fatigue.

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

In BLS, medication administration is not a designated role—this falls under ACLS-level care.

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

Naloxone should only be administered if opioid overdose is suspected.

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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.

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

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

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

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

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

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

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

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

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

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