Clocks spring forward an hour Sunday, March 8.  As Daylight Saving Time arrives, people are encouraged to check batteries in their smoke detectors.  In addition, it’s important for those responsible for Automated External Defibrillators (AEDs) in publicly used buildings including businesses and stores, schools, clinics and churches, to check those potentially life-saving devices.

An AED is used to help those experiencing sudden cardiac arrest. It is a sophisticated, yet easy-to-use, medical devices that can analyze the heart's rhythm and, if necessary, deliver an electrical shock, or defibrillation, to help the heart re-establish an effective rhythm. AEDs are designed for those with no medical training to be able to use in an emergency situation until first responders arrive.

Checking AEDs is as easy as using them. They have a status indicator, or readiness display, that will show an alert when a problem is found. Typically this indicator is on the front or the top of the AED unit. In addition to checking the unit, it is also important to check the electrodes.  Most AED electrodes have an expiration date. AED batteries, also, have either an “install by” or an “expiration” date clearly marked on the outside of the battery.

Most AED units have an internal testing mechanism that is preset on a daily, weekly, or monthly basis.  Depending on the unit, either a status indicator light or an audible prompt will alert there is a problem. The industry standard is to visually inspect AEDs monthly to check the status indicator window. The most common symbols are a green checkmark, flashing light, or the words OK.

On average, batteries need to be replaced every four years, and pads every two years. It is important to refer to the user’s manual as battery replacement can vary. The expiration date for unopened electrodes is clearly marked on the packaging.
