ABSTRACT:
A device for continuously monitoring oxygen consumption and anesthesia gas uptake of surgical patients, having servo-controlled replenishment mechanisms to automatically maintain preset levels of oxygen and anesthesia gas for inhalation. A closed, recirculating delivery circuit is utilized to adminster an appropriate volume of oxygen and anesthesia gas to a surgical patient. An oxygen sensor monitors decreases in oxygen concentration within the recirculatory system and triggers restoration to the preset concentration by means of feedback comparator circuitry. With the oxygen held at the desired level, any volume changes in the system are caused by uptake of anesthesia gas, which is monitored by detecting variations in the expansion of a respirator bellows. The desired amount of anesthesia gas is preset and maintained by a potentiometric monitoring device which produces a voltage proportional to the peak expansion of the bellows. Variations from the preset level of anesthesia gas drive a servo-mechanism for replenishing the anesthesia gas to the preset value. Data relating to oxygen consumption and anesthesia gas uptake are displayed by means of conventional instrumentation.
