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

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

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

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

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

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

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

Chest compressions keep oxygenated blood circulating to the brain and heart until normal function is restored.

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

Visible chest rise confirms that breaths are being delivered effectively.

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

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

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 minimizes interruptions.

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

Equal chest rise confirms proper ventilation and airway placement.

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

Most AEDs are programmed to reanalyze the heart rhythm every 2 minutes.

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

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

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

Defibrillation should be performed as soon as a shockable rhythm is detected by the AED.

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.
