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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

Breaths should be delivered over 1 second each to produce visible chest rise.

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

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

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.

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

For a responsive choking adult, abdominal thrusts (Heimlich maneuver) should be used.

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

High-quality chest compressions are the top priority in cardiac arrest, with ventilation as a secondary focus.

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

Excessive ventilation can cause complications like gastric inflation.

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

Naloxone should only be administered if opioid overdose is suspected.

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.
