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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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.

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

Rescuers should switch every 2 minutes (or 5 cycles of compressions) to maintain high-quality CPR.

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

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

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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.

Visible chest rise confirms that breaths are being delivered effectively.

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

The carotid artery is the preferred site for pulse assessment in unresponsive adults.

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

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

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

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.

Naloxone should only be administered if opioid overdose is suspected.

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

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

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

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

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

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

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