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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

Chest compressions keep oxygenated blood circulating to the brain and heart until normal function is restored.

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

For adults with a pulse but not breathing, provide 1 breath every 5-6 seconds.

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

Naloxone should only be administered if opioid overdose is suspected.
