High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

Pediatric AED pads should be used for children under 8 years old, if available.

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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).

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

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

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

If a choking victim can cough or speak, encourage them to keep coughing rather than immediately performing abdominal thrusts.

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

Encourage the victim to keep coughing instead of immediately intervening.

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

A firm surface is needed to ensure effective compressions.

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

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

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

High-quality CPR for children requires compressing at least 1/3 of the chest depth (about 2 inches or 5 cm).

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

Once an advanced airway is in place, continuous compressions should be given at 100-120 per minute without pausing for breaths.

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

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.

Chest compressions keep oxygenated blood circulating to the brain and heart until normal function is restored.

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

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

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

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

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.
