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

After a shock is delivered, chest compressions should resume immediately to maintain circulation.

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

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

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

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

Once an advanced airway is in place, continuous compressions are given with 1 breath every 6 seconds.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

Equal chest rise confirms proper ventilation and airway placement.

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

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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.

For infants, the correct pulse check location is the brachial artery (inside the upper arm).

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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

Pulse checks should be performed approximately every 2 minutes when providing rescue breathing.

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

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

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

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

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

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

Chest compressions should continue while the AED is charging to maintain circulation.

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

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