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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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.

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

Visible chest rise confirms that breaths are being delivered effectively.

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

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

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

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

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

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

The E-C clamp technique ensures a tight seal while lifting the jaw for an open airway.

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

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

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

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