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

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

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

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

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

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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

Equal chest rise confirms proper ventilation and airway placement.

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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

The first step is to turn on the AED before attaching pads and following voice prompts.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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.
