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

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

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.

High-quality CPR requires minimizing interruptions to maintain circulation.

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

If a patient has a pulse but is not breathing adequately, healthcare providers should provide rescue breathing without chest compressions.

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.

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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.

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

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

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

If there is any doubt about the presence of a pulse, start chest compressions immediately.

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

Visible chest rise confirms that breaths are being delivered effectively.

In a hospital setting, bag-mask ventilation is the preferred method for delivering rescue breaths.

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

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

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.

A firm surface is needed to ensure effective compressions.

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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