A microcomputer-assisted monitoring system provided real-time calculation of cardiorespiratory variables, offering a great advantage during the monitoring and treatment of 30 critically ill patients.
A microcomputer-assisted monitoring system successfully provided real-time calculation and display of cardiorespiratory variables, offering advantages in the management of critically ill patients.
A microcomputer-assisted monitoring system was developed for the continuous measuring and processing of cardiorespiratory variables, including: systemic and pulmonary arterial pressures, CVP, minute ventilation, inspired and expired O2 and CO2 concentrations, temperature, and heart rate. The primary data were converted to digital form, processed, displayed on a CRT monitor, and also stored for later evaluation. This system automatically calculated and displayed on-line and in real-time both primary measurements and derived cardiorespiratory variables, including: oxygen consumption, CO2 production, left and right ventricular stroke work, pulmonary venous admixture, and systemic and pulmonary vascular resistances. Printouts of the variables and trend graphs could be obtained for any desired time period. During its development, we tested this monitoring system in 30 critically ill patients, finding that the real-time calculation of cardiorespiratory variables was a great advantage during monitoring and treatment.
