A firm surface is needed to ensure effective compressions.

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.

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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.

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

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

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

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

Switching roles every 2 minutes ensures high-quality compressions without fatigue.

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

Pulse checks should be limited to 10 seconds to avoid delaying CPR.

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

Excessive ventilation can cause complications like gastric inflation.

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

When a shockable rhythm is detected, defibrillation should be performed as soon as possible.

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).

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

Naloxone should only be administered if opioid overdose is suspected.

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

For suspected spinal injuries, the jaw thrust maneuver is used instead of head tilt-chin lift to maintain spinal alignment.

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

If a patient is unresponsive with a suspected airway obstruction, chest compressions should be initiated immediately to help clear the airway.

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

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

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

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

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

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

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

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