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

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

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

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

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

Naloxone should only be administered if opioid overdose is suspected.

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

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

Shifting the uterus to the left reduces pressure on the inferior vena cava, improving circulation.

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

Equal chest rise confirms proper ventilation and airway placement.

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

For two-rescuer infant CPR, the correct ratio is 15:2, not 30:2.

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

A firm surface is needed to ensure effective compressions.

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

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

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

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