A bag-mask device (BVM) is preferred for healthcare providers as it delivers more effective ventilations.

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

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

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

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

For a responsive choking adult, abdominal thrusts (Heimlich maneuver) should be used.

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

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.

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

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