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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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.

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

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

A firm surface is needed to ensure effective compressions.

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

Infant chest compressions should be at least 1/3 of the chest depth, approximately 1.5 inches (4 cm).

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

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

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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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.

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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