A firm surface is needed to ensure effective compressions.

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

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

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

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

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

CPR should continue until the patient shows signs of life, an AED prompts a shock or no shock, or another trained provider takes over.

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

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

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

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.

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

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

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

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