An automated external defibrillator (AED) is an essential tool for saving lives. When a patient collapses unconscious due to a sudden cardiac arrest, the utilization of AED equipment is vital to restore his heart functions. AED should be employed during cardiopulmonary resuscitation (CPR). If victims are not treated in a time ranging from 4 to 5 minutes (optimal treatment time), survival chances narrow.
A cardiac arrest occurs when the heart’s electrical system malfunctions . It is usually the result of ventricular fibrillation and ventricular tachycardia which eventually leads to cardiac arrests themselves . Though cardiac arrests often are associated with heart attacks, the two conditions are largely different. A heart attack happens when the blood does not reach the heart because of obstructions in the arteries, which causes the heart to be deprived of oxygen.
In most countries, including the United States, ambulances are fully equipped with defibrillators, and emergency situations are managed efficiently by professional paramedics. Defibrillators, every year, save numerous lives and are among the most useful tools when performing cardiac arrest treatments.
However, defibrillator usage is not just restricted to medical personnel. There are different versions designed for specific medical purposes, among which the AED is mainly thought for public use. Therefore it is recommended to be installed in public areas and facilities. Most medical councilsagree that public access to defibrillation equipment should be allowed and could potentially lead to higher survival rates.
To learn CPR techniques and to be qualified to use an AED, a person has to undergo a Basic Life Support (BLS) training program, which is offered by numerous health institutes and non-profit organizations, such as the Red Cross .
To make certain of AED optimal operativity in the event of necessity, it must be regularly checked and cleaned. Mindray has listed exhaustive instructions on how to run maintenance checks and cleaning the device.
Your AED machine should be cleaned on a regular basis, more frequently if located in dusty and heavily polluted places. Before proceeding, consult hygiene regulations of your facility.
|WaterSodium hypochlorite bleach (10%, Sodium hypochlorite)Hydrogen peroxide (3%)Ethanol (75%)Isopropyl alcohol (70%)l Perform classic concentrate OXY (KHSO4 solution)|
Recommended cleaning agents are:
To clean your equipment, please follow these steps:
1. Shut down the appliance, disconnect wires, and remove the battery.
2. Clean the display screen and the external surface of the equipment using a soft cloth dampened with a glass cleaning solution.
3. Wipe off all the solution with a dry cloth.
4. Let the machine dries out in a ventilated, cool place.
Disinfect the toolkit as required in your facility servicing schedule. Before disinfecting, clean the AED console.
Sterilization is not required unless otherwise presented in the Instructions for Use that comes with the product.
It is important to conduct regular maintenance . Check on your AED equipment to determine if it is operating in optimal condition. The following steps can help you to ensure your device upkeep.
●Place the AED device in an easily visible and accessible position, such as the wall of a corridor.
● Verify batteries correct installation.
● Make sure that the status or service light is working properly.
● Assure that the visual and audio alarms are operational.
● Check audio correctly playback. (if the product has audio instruction)
● Thoroughly inspect the exterior of the AED instrument for any signs of damage.
● Ensure that the pads are in optimal condition.
● Control battery lifespan and that the AED is with enough electricity.
●Always keep a record of AED periodical inspection to ensure it is done regularly and thoroughly.
● For any clarification, refer to the instruction manual.
