Medical AED cabinets and brackets are used to store Automated External Defibrillators (AEDs) in a secure and easily accessible location in case of an emergency. AEDs are used to treat sudden cardiac arrest and can be found in public places like airports, schools, and shopping malls. Cabinets and brackets come in a variety of sizes and materials and can be mounted on a wall or placed on a stand. Some cabinets also come equipped with an alarm to alert others in case the cabinet is opened or tampered with. It's important to regularly inspect and maintain AEDs and their cabinets/brackets to ensure they are in proper working order in case of an emergency.
