An Automated External Defibrillator, or AED, is a portable medical device designed to deliver an electric shock to restore a normal heart rhythm during sudden cardiac arrest. This condition occurs when the heart’s electrical activity becomes chaotic, preventing it from effectively pumping blood. AEDs are specifically engineered for ease of use, guiding rescuers with voice prompts and visual cues. Their presence in public spaces allows immediate intervention, significantly increasing the chances of survival for someone experiencing this life-threatening event.
Why Regular Checks are Essential
Regular checks ensure an AED is always ready for immediate use. Device failure during sudden cardiac arrest can have severe consequences, as every minute without defibrillation decreases a person’s chance of survival by 7% to 10%. Inspections prevent such failures, confirming the device will function as intended when a life depends on it. Maintaining AEDs in proper working order also contributes to public safety and accountability.
Proper maintenance is often encouraged or required by various safety guidelines and regulatory bodies. Organizations and individuals responsible for AEDs benefit from adhering to these guidelines, as it helps them meet their duty of care.
Standard Inspection Schedules
AEDs require a multifaceted inspection approach. Many models perform automatic self-tests daily, weekly, or monthly, verifying their internal circuitry, battery, and pads are functional. These automated checks are indicated by a status light, often green, signaling the device is operational.
Beyond automated self-tests, manual inspections are recommended at regular intervals. A quick visual check ensures the AED is present, unobstructed, and its indicator light shows readiness. More comprehensive monthly checks involve visually inspecting the unit for damage, confirming the integrity of electrode pads, and checking battery status.
It is important to inspect an AED immediately after each use. This post-use check involves replacing used pads and batteries. Manufacturer guidelines are the primary resource for specific maintenance schedules, providing model-specific instructions for proper performance. Additionally, some state or local regulations may mandate particular inspection frequencies, reinforcing adherence to these guidelines.
What to Check During an Inspection
A comprehensive AED inspection involves several components to verify operation. The indicator light or status display is a primary check; a blinking green light usually signifies the device is ready for use, while a red light or chirping sound indicates a problem requiring attention. Addressing these alerts promptly is necessary for maintaining readiness.
Checking expiration dates on electrode pads and batteries is an important step. Electrode pads have a shelf life because the water-based gel that ensures adhesion and conductivity can dry out over time. Expired pads may not adhere properly or deliver an effective shock. Similarly, AED batteries usually last two to five years in standby mode, and their expiration date must be noted and adhered to.
Inspect the physical condition of the AED unit for damage. Ensure the associated rescue kit contains accessories such as paramedic scissors, a razor for chest hair removal, gloves, and a CPR barrier mask. These items are important for efficient and safe application of the AED.
Ensuring Ongoing Operational Status
Maintaining an AED program extends beyond routine physical checks to include administrative practices. Comprehensive documentation and record-keeping are important for compliance with regulations and for demonstrating due diligence if the device’s readiness is ever questioned. This includes recording the date, time, and findings of all inspections.
Designating an AED coordinator or a responsible party is important for overseeing the inspection schedule and managing the maintenance program. This individual ensures all checks are performed consistently and any issues are addressed promptly. Their role involves coordinating with manufacturers for replacements and ensuring adherence to established protocols.
If an issue is identified during an inspection, immediate corrective action is necessary. This may involve replacing expired pads or batteries, cleaning the unit, or contacting the manufacturer for repairs. After an AED has been used in an emergency, it requires post-incident review and replenishment. All used components must be replaced to ensure the device is ready for subsequent use.
