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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

Chest compressions maintain circulation and deliver oxygenated blood to the brain and heart.

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

If a patient has a pulse but is not breathing adequately, healthcare providers should provide rescue breathing without chest compressions.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

An AED analyzes the heart rhythm and delivers a shock if a shockable rhythm is present.

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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

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

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

Visible chest rise confirms that breaths are being delivered effectively.

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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