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

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

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

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

A firm surface is needed to ensure effective compressions.

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

Once an advanced airway is in place, continuous compressions are given with 1 breath every 6 seconds.

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

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

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.

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

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

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

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

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

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

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

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

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

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

For suspected spinal injury, the jaw thrust maneuver should be used instead of head tilt-chin lift.

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.

A firm surface is needed to ensure effective compressions.

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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.

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

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

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

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

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

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

Agonal gasps are not normal breathing and should not delay CPR.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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