[An automated electronic anesthesia record and automated urine output measurement].
We can now collect many parameters (NIBP, HR, ABP, SpO2, EtCO2, CCO, etc) from an anesthesia monitor in an automated electronic anesthesia record system. The function of automated urine output measurement has been added to an automated electronic anesthesia record system. A digital weight meter connected with a personal computer by RS-232 C is used to measure the weight of urine. We convert the weight to the volume hypothesizing that the density of urine is 1 g.ml-1. Physiologic parameters are recorded every 10 seconds from an anesthesia monitor and we can set the period of automated urine output measurement we like. We must enter the initial and final urine output but the intraoperative urine output is collected automatically to an automated electronic anesthesia record and visualized in urine bar graph. The total volume of urine is calculated. Computerized urine output measurement can record data more frequently, for example, every 10 minute. At the end of the operation, intraoperative data are sent to a host computer and the anesthesia record is printed. Combining the automated urine output measurement with an automated electronic anesthesia record system is useful in anesthesia practice of a long operation.
