End Tidal

The use of a small digital computer to control a number of interactive physiological variables is demonstrated. It is shown that by monitoring the values of end tidal per cent CO2, inspired O2 percentage and mean arterial blood pressure, a computer-controlled system can regulate the ventilation and anaesthesia of an animal within fine tolerances. Similarly it is shown that by controlling the infusion of muscle relaxant, the integrated electromyogram of a muscle can be maintained at any desired level. The computer control system automatically allows for random disturbances in system parameters in maintaining set levels of the controlled variables. The system responds rapidly to changes in the desired level of variables, and prescribed time courses of variables can be followed.

Broad Outline

The use of digital computer methods to control aero gas turbines is comparatively new. The paper attemps to cover their background and essential features in broad outline. It discusses the special properties of digital computer control systems in relation to hydromechanical and electric analog arrangements and the special problems of design and safety involved. Some results of practical tests on a large complex engine are presented and discussed, special emphasis being given to those techniques which are particular to digital systems. The paper finally suggests the directions in which future developments of these systems might move.
