| Abstract: | Control of a number of interactive physiological variables by an online computer, operating in real time, is demonstrated. It is shown that a computer-controlled system, by monitoring values of arterial blood pressure, end-tidal CO2 percentage and inspired O2 percentage, can maintain the respiration and anaesthesia of a ventialted animal within close tolerances. Under computer control, it is possible to compensate for random disturbances of the system parameters, and changes in the desired levels of the variables can be dealt with automatically. |
