Automated External Defibrillator (AED) ™ Procedure

1. Purpose

The Automated External Defibrillator (AED) is a portable device that delivers an electric shock to the heart to reverse sudden cardiac arrest, the sudden and life-threatening onset of a chaotic and unproductive heart rhythm. Cardiac arrest claims more than 350,000 lives outside the hospital annually. Published studies have proved that early defibrillation, within the first few minutes of cardiac arrest, can save up to 30 percent of victims.

The window of survival for sudden cardiac arrest victims is usually less than seven minutes, making it critical to administer defibrillation quickly. According to the American Heart Association, for every minute that passes after cardiac arrest, a victim's chance of survival decreases by 10 percent, and the potential for brain damage can occur as early as five minutes. The national survival rate for sudden cardiac arrest is currently five percent. With widespread AED deployment, these survival rates can increase dramatically.

2. Responsibilities

Morgantown NIOSH Safety Office:

1. Will provide training on the use of the Power Heart AED™ to the NIOSH Security Office and NIOSH staff.

2. Will provide the use of the Power Heart™AED to the NIOSH field teams.

3. Will perform as required maintenance to all AED units and arrange for servicing when the units indicate a problem.

4. Will print out, review, and record all AED diagnostic self tests monthly on the maintenance log sheets.

5. Will maintain records for yearly review by the healthcare provider who provides medical oversight for the AED program.

3. Definitions

Ventricular Fibrillation

Ventricular fibrillation (VF) is the chaotic electrical activity in the heart that causes most cardiac arrests. The chaotic electrical activity results in uncoordinated contractions that produce no blood flow and no pulse. When a heart is in VF, oxygenated blood will not reach the brain, causing irreversible damage to the brain within 5 minutes and patient death within 10 to 15 minutes.

Defibrillation

Defibrillation is the process that can stop the chaotic heart rhythm of ventricular fibrillation by delivering an electrical current through the heart. External defibrillation is the delivery of a controlled DC electrical current through the chest of a victim in cardiac arrest. This high-energy electric shock is the only effective treatment for VF. A successful defibrillation shock or pulse stops the chaotic rhythm and allows the normal electrical activity and blood-pumping functions of the heart to resume.

5. Procedure

Pre-Rescue Safety Information:

· Exercise caution when operating the AEDs close to flammable gases.

· Do not operate wireless communication devices (cell phones, FM 2-way radios etc.) near the AED units. Radio frequency interference may cause incorrect readings and incorrect shock advisory.

· Disconnect data communication serial cable from the AED units if it is connected.

· Do not use AED units on individuals younger than 8 years of age.

Performing the Rescue

If you see someone who is unconscious immediately have someone call 9-911 and retrieve an AED unit. If the rescuer is not able to readily retrieve a unit, he or she may have someone else acquire a unit for them. The security desk will receive the call and ask the contact if they have a 911 emergency. If yes, security will immediately initiate a 911 conference with the individual. The individual should remain on the phone and give the following pertinent information:

a. Location of emergency

b. Type and extent of the emergency

c. Name and telephone number Assessing the patient:

Patient must exhibit all of the following prior to using the AED unit:

· Unconsciousness

· Not breathing

· No pulse First Save AED procedure:

Open the AED lid to turn unit on. After the unit performs the self test follow the voice prompts.

Open the electrode packet and place the self-adhesive electrodes on the bare chest of the patient as illustrated Appendix B. Shave chest hair if necessary. If victim’s chest is dirty or wet, wipe the chest clean and dry.

1. AED Voice prompts:

· “Tear Open Package and Remove Pads”

· “Place electrodes”

· “Do not touch patient! Analyzing rhythm.”

If a shockable rhythm is detected follow these voice prompt instructions:

· “Shock advised. Charging

· “Stand clear! Shock will be delivered in”

· “Three, two, one.”

· “Shock delivered”

· “It is now safe to touch the patient” Note:

If electrodes are not properly positioned, the voice prompt will say, “Check electrodes”. Check that the electrodes are placed firmly on clean dry skin and the electrode cables are properly attached to the AED unit.

If the patient’s rhythm change to a non-shockable rhythm before the actual shock is delivered, the AED will override the charge. The voice prompt will say, “Rhythm changed, shock cancelled.” Perform CPR if there is no pulse.

2. The AED has been reprogrammed to 2005 American Heart Association Guidelines. One shock will be delivered followed by immediate CPR. The AED will check the victim’s rhythm after 5 cycles (approximately 2 minutes) of CPR. Once the patient is conscious and breathing normally, wait for Advanced Life Support (ALS) to arrive to the scene. Continue to follow the voice prompts until ALS arrives.

3. Disconnect the electrodes from the AED unit, and transfer the patient to ALS with the electrodes still attached to the patient.

4. Close the lid of the AED unit after a rescue and deliver it to the Safety Office.

Post-rescue process

1. Connect a new pair of electrodes to the AED.

2. Check electrode expiration date and place electrode expiration date sticker on outside of the lid of the AED.

3. Verify that the “Replace” indicator light is not lit. Replace battery if indicator is lit.

4. Close lid and verify the “Status” indicator on the AED handle is green.

5. Retrieve data from the AED unit prior to using unit for another save.

6. Record Keeping

The Safety Office will make the AED units available to the patient’s physician for downloading data for review.
