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

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

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

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

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

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

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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.

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

Pediatric AED pads should be used for children under 8 years old, if available.

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

Visible chest rise is the best indicator that rescue breaths are effectively ventilating the lungs.

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

If a choking victim becomes unresponsive and pulseless, CPR should begin immediately, starting with compressions.

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

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