For two-rescuer pediatric CPR, the correct compression-to-ventilation ratio is 15:2.

For two-rescuer infant CPR, the correct compression-to-ventilation ratio is 15:2.

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

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

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

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

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

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

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

Visible chest rise confirms that breaths are being delivered effectively.

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

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

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

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

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

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

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

If a choking victim becomes unresponsive, emergency services should be activated, and CPR should begin immediately.

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

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.

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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.

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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