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

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

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

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

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

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

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

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

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

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

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

For adult CPR, compressions should be performed with two hands, one on top of the other, placed on the lower half of the sternum.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

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

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

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

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

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

Equal chest rise confirms proper ventilation and airway placement.

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

Unless a valid DNR order is confirmed, resuscitation efforts should begin.

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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