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

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

A firm surface is needed to ensure effective compressions.

CPR should continue until the patient shows signs of life, an AED prompts a shock or no shock, or another trained provider takes over.

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

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

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

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

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

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

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

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

Visible chest rise confirms that breaths are being delivered effectively.

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

A firm surface is needed to ensure effective compressions.

Unlike adults, the most common cause of cardiac arrest in infants and children is respiratory failure leading to hypoxia.

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

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

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

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

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

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

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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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