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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

Switching roles every 2 minutes prevents rescuer fatigue and ensures continuous, high-quality CPR.

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

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

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

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

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

Gasping (agonal breathing) is not normal breathing and should not delay CPR.

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

The best method is to tap the patient and shout to assess for responsiveness.

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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

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

For a responsive choking adult, abdominal thrusts (Heimlich maneuver) should be used.

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

Encourage the victim to keep coughing instead of immediately intervening.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

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

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

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

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

Equal chest rise confirms proper ventilation and airway placement.

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