We have developed an inexpensive mobile computer system for the operating room. This system utilizes an IBM AT computer, 1200 baud modem, wide carriage dot matrix printer, serial interface card and Adalab-PC data acquisition hardware for continuous patient monitoring and data storage. The computer currently interfaces with the main monitor, blood gas machine, heart-lung machine and five Yellow Springs 400 series temperature probes. Flexibility has been built into the software to allow for the use of in line blood gas monitors, centrifugal pumps and up to sixteen continuously recorded parameters. Case data is stored under the patient's hospital number in ASCII disk files and can be transferred to the hospital mainframe computer for detailed statistical analysis.
Patient data is displayed on a color monitor during the case and is automatically printed as a permanent record when the patient leaves the surgery suite. Detailed information, calculated values, pressure trend graphs, temperature trend graphs and event timers are available through simple keystroke commands which change the screen on display.
The software is written by a perfusionist in the easily understood and modified Basic programming language. Under experimental conditions, this program has been used to control the heart-lung machine through the use of established algorithms.
