Nexan is a medical device company that has developed an easy to use, wireless, monitoring system for collection of physiological data from a patient's home. A variety of cardio-respiratory parameters are captured continuously without disrupting the patient's lifestyle.  The parameters measured by the ClearPath System include continuous 2 (or 3) lead ECG, respiration rate & pattern and blood oxygen saturation. In addition, point-in-time measurements of blood pressure, lung function (PEF, FEV1 and FVC) and weight can be made. The system also includes event buttons that allow patients to indicate when events, e.g. palpitations, occur. The time of these events is marked, and the cardio-respiratory activity occurring at that time can be viewed.  The main benefits of the system are expected to be as follows: Additional information on drug effects: *Multiple physiological parameters monitored simultaneously  *Continuous monitoring over several consecutive days  *Avoidance of the 'white coat effect'.  Improved data management processes:  *Electronic data capture  *Real time access to data direct from patient's home.  May improve trial safety and follow-up:  *Patient monitoring between clinic visits.  May improve patient compliance:  *System includes prompts and reminders to patients.  Note: The ClearPath System represents Nexan's third generation of wireless patient technology, and was FDA 510k cleared for commercial distribution in the US on September 4, 2001
