Understanding AED Expiry Dates: A Comprehensive Guide to Pads and Batteries for AEDs in Canada
Automated External Defibrillators (AEDs) are critical tools in the fight against sudden cardiac arrest. These life-saving devices are designed to deliver an electric shock to the heart, restoring its normal rhythm. However, for AEDs to be effective when needed, it's crucial that they are well-maintained, which includes keeping track of the expiry dates for their pads and batteries.
