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

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 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 recommended compression rate is 100-120 compressions per minute.

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

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

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

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

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

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

Single-rescuer infant CPR follows the 30:2 compression-to-ventilation ratio, just like adults.

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

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

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

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

To minimize interruptions in care, breathing and pulse checks should be performed simultaneously, taking no more than 10 seconds.

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

Naloxone should only be administered if opioid overdose is suspected.

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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