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

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

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

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

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

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

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

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

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

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

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

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

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

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

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 minimizes interruptions and maintains high-quality CPR.

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

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

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

In BLS, medication administration is not a designated role—this falls under ACLS-level care.

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

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

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

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

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

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

A firm surface is needed to ensure effective compressions.

If a choking victim can cough or speak, encourage them to keep coughing rather than immediately performing abdominal thrusts.

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

Excessive ventilation can cause complications like gastric inflation.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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