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

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

If there is any doubt about the presence of a pulse, start chest compressions immediately.

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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

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

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

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

Over-ventilation can lead to increased intrathoracic pressure, reducing venous return and cardiac output.

Encourage the victim to keep coughing instead of immediately intervening.

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

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

A firm surface is needed to ensure effective compressions.

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

Excessive ventilation can cause complications like gastric inflation.
