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

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

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

In a hospital setting, bag-mask ventilation is the preferred method for delivering rescue breaths.

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

The two-thumb encircling hands technique is the preferred method for two-rescuer infant CPR, as it provides better depth and control.

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

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.

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.

Visible chest rise confirms that breaths are being delivered effectively.

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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.

Switching roles every 2 minutes minimizes interruptions and maintains high-quality CPR.

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

Naloxone should only be administered if opioid overdose is suspected.

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