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.

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

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

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

Gasping (agonal breathing) is not normal breathing and should not delay CPR.

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

Rescuers should switch every 2 minutes to maintain high-quality CPR and prevent fatigue.

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

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

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

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

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

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

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.

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

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

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

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

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

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

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