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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

Early defibrillation is the most critical step in increasing survival rates for patients in cardiac arrest with a shockable rhythm.

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

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

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

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

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

For infants, the correct pulse check location is the brachial artery (inside the upper arm).

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

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

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

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

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

For two-rescuer pediatric 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.

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

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

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

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

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

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.

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

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

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

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

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

The two-thumb encircling hands technique is the preferred method for two-rescuer infant CPR, as it provides better depth and control.

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

Naloxone should only be administered if opioid overdose is suspected.

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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