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

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

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

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

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

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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

For a choking infant, back slaps and chest thrusts should be used instead of abdominal thrusts.

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

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

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

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

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

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

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

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

Shifting the uterus to the left reduces pressure on the inferior vena cava, improving circulation.

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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.

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

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

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

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

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

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

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

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

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.

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.

The correct compression depth for adult CPR is at least 2 inches (5 cm).

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