Understanding the Effects of Extreme Temperature on Your AED
In an ideal world, our AEDs would thrive in constant, pleasant weather conditions of around 75°F year-round. However, reality doesn't always align with our wishes. Similar to laptops or tablets, an AED is an electronic device that shouldn't be subjected to extreme heat or cold.
Impact of Heat on Your AED
Extreme heat poses various risks. For instance, in regions like the Southwest with scorching temperatures surpassing 110°F, the internal circuitry of the AED may melt, leading to malfunction. Additionally, high temperatures can affect the lifespan of lithium batteries.
Most AED manufacturers recommend standby and operating temperatures ranging between 32°F and 122°F (0°-50°C). It's essential to note that temperatures inside a car can soar much higher than the outside temperature on a hot day. For example, on a 90°F day (within the manufacturer's guidelines), a car left in the sun can reach temperatures exceeding 130°F.
Consider your AED's temperature specifications when deciding its storage or placement. Placing it in a cabinet exposed to afternoon sun or an outdoor location without shelter might not be safe for the device.
AEDs in Extremely Cold Conditions
Your AED isn't resilient to extreme cold either. Cold weather can impact the electronic functionality of the device differently than causing internal circuitry to melt. Despite the alcohol-based adhesive in AED electrode pads being less prone to losing adhesion in cold temperatures, the cold itself can affect the AED's electronics. A firsthand account from one of our customers illustrates this issue.
Wes Wagoner, a lead product trainer at AED Superstore, shared an incident where an AED was left in below-freezing temperatures for weeks in a vehicle. Upon realizing the mistake and attempting to turn it on indoors, it took several days for the unit to thaw and become operational, potentially posing a critical issue if immediate use had been necessary.
Preserving Your AED's Readiness for Rescue
While some AEDs are designed to withstand tough conditions, it's crucial to adhere to the manufacturer-recommended temperature range to prevent damage or temporary operational disruptions:
☀️ If outdoors, keep it shaded from direct sunlight, especially at events. ☀️ Use a marked insulated bag or cooler to transport your AED and ensure easy access when needed. ☀️ If stored in a vehicle, keep it inside the air-conditioned cabin and away from sunlight, especially if parked for extended periods. ☀️/❄️ Bring your AED indoors during evenings if stored in a vehicle. ❄️ In cold weather, store the AED in the heated cabin of the vehicle, not in the trunk, and bring it inside overnight. For temperature-controlled storage options, consider AIVIA cabinets available at AED Superstore, equipped with features like heaters or fans to maintain suitable temperatures, ensuring your AED remains ready for action as needed.
