title: Wireless vital sign telemetry to hand held computers.
abstract: Most physicians and other health care providers share/access patient information via hard copy chart records, telephone conversations, or through hospital computer networks. These modalities are cumbersome when physicians are away from the hospital and ground wiring infrastructure is not readily available. In a prior study, we used wireless in-flight telephony and the Internet to transmit vital signs from an airborne Boeing 757 to three remote locations on the ground. However, because all recipient stations relied on an institutional network to receive the information, it was not possible to transfer data to a given location beyond the hospital campus. We now propose an innovative system capable of transmitting telemetry information from any location in the globe to a single portable computer using Wireless Application Protocol (WAP) technology for the Internet. Medical data including blood pressure, pulse, respiratory rate, end tidal CO2, oxygen saturation and EKG tracings were transferred from a G2 (digital cellular) phone linked to a hand held computer to a remote hand held device and were viewed in real time using customized software. Cellular Digital Packet Protocols (CDPD) enabled data transfer speeds up to 19,200 bps. Advances including the Internet and wireless computer technology may revolutionize the way medical information is shared, making it possible for physicians and health allies to directly access patient data from anywhere at any time.
