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

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

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

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

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

Equal chest rise confirms proper ventilation and airway placement.

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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.

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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

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

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.

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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