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

Encourage the victim to keep coughing instead of immediately intervening.

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

Chest compressions maintain circulation and deliver oxygenated blood to the brain and heart.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

The best method is to tap the patient and shout to assess for responsiveness.

Breaths should be delivered over 1 second each to produce visible chest rise.

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

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.

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

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