[On-line data management system using a portable blood gas analyzer in the operating room].

It is very important to establish a clinical testing system which is not only prompt, simple and accurate but also safe for the patients and medical staff in the operating room, emergency room and intensive care unit. In our institution an i-STAT portable blood gas analyser has been widely used for point of care testing in all the operating rooms. This clinical testing system has been upgraded by adding an i-STAT communication protocol to our online data management system. The analysed data transmitted by the i-STAT as an infrared signal is transformed to an electronic signal through the IR link and sent to the central data station (CDS) via RS232C. The data received by the CDS is then sent to the upper grade computer system where the data is recorded on the hard disk. One advantage of this system is that it is connected to the hospital computer system. Not only does this new system meet the need for accurate, safe, effective and economical laboratory testing, but also retrospective and multifactorial analysis of intraoperative events can be easily carried out. In the future this system can be applied to telemedicine through the Internet and contribute to the treatment of critically ill patients.
