The Medicines and Healthcare products Regulatory Agency (MHRA) is advising the public to take precautions to ensure their medical equipment continues to function safely during periods of hot weather. The agency highlights that devices including insulin pumps, continuous glucose monitors (CGMs), portable oxygen concentrators, hearing aids, and electric-powered mobility equipment can be affected by heat, direct sunlight, humidity, and sweat.
Rob Reid, MHRA Deputy Director for Innovative Devices, stated that millions of people rely on medical devices daily and that extreme heat can affect their operation. He recommended keeping devices out of direct sunlight, avoiding leaving them in hot cars, and being aware of issues like sweat. Users should also follow manufacturer instructions for storage and operating temperatures to reduce the risk of problems.
The MHRA suggests checking manufacturer instructions for recommended operating and storage temperatures, keeping devices away from excessive heat and moisture, and inspecting them for damage before use. If a device stops working, displays an error message, or appears to be affected by heat, individuals should know what steps to take, including any backup arrangements recommended by a healthcare professional or the manufacturer.
