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

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

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

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

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

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

Equal chest rise confirms proper ventilation and airway placement.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

Visible chest rise is the best indicator that rescue breaths are effectively ventilating the lungs.

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

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

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

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

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

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

Switching roles every 2 minutes prevents rescuer fatigue and minimizes interruptions.

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

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

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

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

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

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

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

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

The two-thumb encircling technique is preferred for two-rescuer infant CPR, while single rescuers typically use two fingers.

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

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

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

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

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

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

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

For infants, responsiveness is assessed by tapping the bottom of the foot and shouting.

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

Equal chest rise and fall confirms proper ventilation and airway placement.

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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