The LifeShirt is a noninvasive ambulatory monitoring device that continuously monitors and stores respiration and ECG onto a CompactFlash™ memory card within a portable battery powered Handspring Visor® worn on a belt or within a pocket. The patient may be located at home or in an alternate care setting. The monitored subject can enter symptoms, activities, and medications into the Handspring Visor® that becomes part of the digital data stream. An optional NONIN pulse oximeter and Critikon noninvasive blood pressure monitor can be connected into the Visor for recordings during sleep or defined activities. The purpose of this system is to collect and store cardiac, respiratory, and blood pressure data as well as body position, various types of activities annotated with symptoms and a medication diary for subsequent analysis and archival at a data center utilizing the VivoLogic 1.0 software program. Data is transferred to the data center generally after the end of a patient data recording session.
