A portable electronic device that detects irregular heartbeats that may pose a life-threatening threat is an Automated External Defibrillator (AED). The use of this particular instrument comes with some risks. It is not recommended to use this device in a wet environment. To prevent shocks from traveling through the water and not the heart, you must dry the victim's chest before applying any electrical pads. Towels are often included in defibrillators to allow the skin to dry. Before applying electrical shocks to a victim, direct others to stand clear of the victim. It is important to avoid touching the body as it conducts electricity as well. It is also important to never use this device in a room with combustible vapors. An explosion or fire can occur if sparks are generated. To use this device properly, you should receive training. It is possible to harm someone if you do not receive training. 

AEDs require regular maintenance to function properly. This means your AED supplies must be regularly checked and replaced, as well as the unit being tested. Lack of maintenance could lead to a serious malfunction, which would eliminate the usefulness of the device. Individuals can manage the AED with dedicated software and mobile apps to ensure it is in proper working order.  A typical AED can continue to work in standby and operating temperatures between 32F and 122F (0C - 50C). That said, temperatures above 110F may begin to cause issues.  The electrode pads may also lose their effectiveness by drying out in extreme conditions. These temperatures can be reached if the device is left in direct sun or a hot vehicle. Additionally, extreme cold can also cause malfunctions or reduced lifespan. It is important to not let the AED freeze. If it does freeze, it may take a couple of days to thaw and resume functioning freezing.

AEDs are portable electronic devices designed to deliver an electric shock to the heart in cases of sudden cardiac arrest. In addition to environmental considerations and maintenance, another critical aspect of AED's risk analysis is the potential for user error. Training and familiarity with the device are crucial to ensuring effective and safe use during a cardiac emergency. Lack of proper training may lead to incorrect placement of electrodes or delays in initiating the life-saving shocks. Moreover, it's essential to address the psychological impact on users during high-stress situations, as anxiety or panic could impact decision-making and performance. Evaluating the probability of user error requires assessing the quality and frequency of training programs, while the severity would depend on the promptness and accuracy of response in a real-life emergency scenario. Furthermore device compatibility/battery replacement needs to be considered as a risk in times of usage. The probability of battery-related issues can be mitigated through regular checks and adherence to recommended replacement schedules, with severity ranging from temporary unavailability to a complete failure during a cardiac event.

Potential risks associated with AEDs include improper electrode placement, device malfunction, and environmental hazards. Improper placement often occurs due to user error, with the probability depending on the quality of training, and the severity being high as it could delay life-saving treatment. Device malfunction is another risk, often linked to inadequate maintenance, with the probability increasing over time and the severity ranging from moderate delays to complete failure. Environmental hazards, such as wet or combustible surroundings, also pose risks, with the probability depending on the deployment context and the severity being high due to potential electrical shocks or explosions. Evaluating these risks involves assessing their likelihood and impact while implementing measures like regular training, maintenance schedules, and proper storage practices to mitigate them effectively.
