Computer assisted transcutaneous oxygen monitoring.

A computerized system for acquisition of data from a transcutaneous PO2 (PtcO2) monitor is presented. A North Star Computer, Inc., "Horizon" microcomputer was used in this system. The PtcO2 monitor was a Radiometer TCM-1 equipped with an external printer interface. The system had a custom interface module to accept binary-coded decimal data from the PtcO2 monitor. In addition, a 16-channel, 12-bit A/D module, a real-time clock module with interrupt capability, and a high-resolution graphics module were incorporated.
