A Cellular Medical Alarm With GPS Helps Save Lives

By Sally Delacruz


The generation that became known as baby boomers vowed during the sixties to never grow old, but that promise has predictably evaporated. Today, this aging demographic group is most concerned about the issues of independent senior living, including the realistic possibility of needing to call for emergency medical attention. Having access to a cellular medical alarm with GPS helps assuage those fears.

Alarmingly, one in three senior citizens falls each year. Although some try to hide this fact from their doctors in an effort to avoid losing personal autonomy, falls are the primary cause of significant injury in older people, often leading to hospitalizations and permanent disability. If an accident occurs when alone, there is a good chance that help might not arrive until it is too late.

Demand for a personal, easy-to-use alarm system that automatically summons an ambulance originally prompted the earliest development of these devices. Pioneering models used a simple network featuring a remotely activated speaker phone. When active, it could connect directly via a hands-free land line to an emergency dispatch center. This was a great improvement, but still had limited range and portability issues.

Subsequent improvements include communications pendants worn around the neck. When activated, they automatically connect to the speaker phone, which calls for help via a land line. These systems are still quite popular, although limited to in-home use. Some also include sensor technology that summons aid when a victim cannot talk. Most have an available monitoring service, while others are simply programmed to call 911.

While that technology is quite helpful, there have been recent updates adding services unavailable just a few years ago. The same principles that made these alarms so popular for home use are now able to summon help no matter where the wearer goes. The new devices link personal, portable units to a cell phone network having GPS location capabilities.

Although there are concerns about digital surveillance, this is one form of tracking that has been welcomed. All smart-phones today come with the GPS tracking activated, and most users do not take the time to deactivate that feature. Based on the last recorded call, satellites are able to triangulate a signal between cell towers, revealing its precise origin.

When a sick or confused older person pushes the help button, it not only displays their personal identification information, but also their current whereabouts. The caller enjoys voice communications with an emergency center, and can usually contact help from any spot that has cell phone coverage. Unlike an actual smart-phone, the units are small enough to be worn, are waterproof, and easy to see.

When activated, some service care centers are also able to provide important medical information for first responders before they arrive. When a senior in distress does not actually know his or her location, help can still be on the way within minutes. Like cell phones, these devices must be recharged periodically, and have a similar life expectancy, but the additional security advantages they offer are worth that minor inconvenience.
