3-AXIS ACCELEROMETER BASED FALL MONITORING SYSTEM

ABSTRACT:

          Falls are one of the most common adverse events in hospitals and fall management remains a major challenge in the medical care quality. Falls in patients are associated with major health complications that can result in health decline and increased medical care cost. To deliver medical care in time, reliable location-aware fall detection is needed. In this paper, we propose a patient alert alarm for fall management. It is SMS location awareness fall detection system that provides immediate position information to the care givers as soon as the fall happened. Obviously, the integration of location awareness and fall detection technologies fulfills the requirements of delivering critical information to relative professions and improve the medical care quality.

This project gives the location awareness such as in-time information about the location of their patients, doctors, and medical staffs when medical emergencies arise .For example, inpatients might fall somewhere in the hospital during the midnight, a patient alert alarm system for fall management provides location information to the night shift nurses. In this project, we use a location-aware fall detection system by using tri-axial accelerometers as fall detecting sensors.

An accelerometer is a device that measures proper acceleration (“g-force”). Proper acceleration is not the same as coordinate acceleration (rate of change of velocity). For example, an accelerometer at rest on the surface of the Earth will measure an acceleration g= 9.81 m/s2 straight upwards.
