Ubiquitous mobile access to real-time patient monitoring data

An application "Pocket WinView" was developed for a Pocket PC personal digital assistant device, which allows remote access to near real-time physiological information from a patient monitor on a commercial handheld device (iPAQ, Pocket PC). The application provides continuous display of up to six monitored physiological waveforms and parameter values. Wireless communication can be established using Wireless LAN and general packet radio service (GPRS). Data is protected with hybrid public key encryption. User authentication is required every time the application is started. Patient data can also be stored on Compact Flash memory cards for data collection purposes. Additional integration with Web-based applications on the hospital intranet make it possible to combine the near realtime signals with previously recorded 12-lead ECGs, laboratory test results, and charting information.
