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

For children, compress the chest at least 1/3 of its diameter (about 2 inches or 5 cm).

High-quality CPR requires minimizing interruptions to maintain circulation.

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

For a choking infant, back slaps and chest thrusts should be used instead of abdominal thrusts.

Encourage the victim to keep coughing instead of immediately intervening.

Clear role assignment and minimizing interruptions optimize CPR quality in a team setting.

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

If a choking victim can cough or speak, encourage them to keep coughing rather than immediately performing abdominal thrusts.

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

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

Equal chest rise confirms proper ventilation and airway placement.

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

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

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

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

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

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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

Rescuers should switch every 2 minutes to maintain high-quality CPR and prevent fatigue.

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

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

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

A bag-mask device (BVM) is preferred for healthcare providers as it delivers more effective ventilations.

Closed-loop communication ensures that orders are acknowledged and carried out correctly.

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

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