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

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

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

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

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

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

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

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

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

If a choking victim can cough or speak, encourage them to keep coughing rather than immediately performing abdominal thrusts.

High-quality chest compressions help circulate oxygenated blood to the brain and heart.

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

Equal chest rise confirms proper ventilation and airway placement.

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

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

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

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

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

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