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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

Rescue breathing should be initiated for a patient with a pulse but no normal breathing.

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

Clear role assignment and minimizing interruptions optimize CPR quality in a team setting.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Over-ventilation can increase intrathoracic pressure, reducing venous return and cardiac output.

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.

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

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

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

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

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

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

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

The two-thumb encircling technique is preferred for two-rescuer infant CPR, while single rescuers typically use two fingers.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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