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

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

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

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

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

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

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

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

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

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

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

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

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

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

An AED is used on patients who are unresponsive, pulseless, and not breathing.

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.

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

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

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

Gasping (agonal breathing) is not normal breathing and should not delay CPR.

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

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

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

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

Encourage the victim to keep coughing instead of immediately intervening.

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

A firm surface is needed to ensure effective compressions.

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.

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

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.

A firm surface is needed to ensure effective compressions.

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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