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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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.

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

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

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

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

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

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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

Equal chest rise confirms proper ventilation and airway placement.

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

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

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

A bag-mask device (BVM) is preferred for healthcare providers as it delivers more effective ventilations.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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