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

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

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

Switching roles every 2 minutes ensures high-quality compressions without fatigue.

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

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

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

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

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

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

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

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

Switching roles every 2 minutes prevents rescuer fatigue and minimizes interruptions.

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

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

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.

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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.

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

Shifting the uterus to the left reduces pressure on the inferior vena cava, improving circulation.

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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