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

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

Visible chest rise is the best indicator that rescue breaths are effectively ventilating the lungs.

For adult CPR, compressions should be performed with two hands, one on top of the other, placed on the lower half of the sternum.

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

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

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

For children with a pulse but no normal breathing, provide rescue breaths at a rate of 12-20 per minute.

For adults with an advanced airway, ventilation should be given at a rate of 1 breath every 6 seconds.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

A firm surface is needed to ensure effective compressions.

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

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

A firm surface is needed to ensure effective compressions.

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.

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

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

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

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.

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.

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

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

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

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

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

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

Agonal gasps are not normal breathing and should not delay CPR.

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.

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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.

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