Systems and methods for controlling gas compositions in surgical cavities during endoscopic surgery procedures

摘要

Methods for controlling the gas composition within a surgical cavity during an endoscopic surgical procedure include monitoring multiple gas species in a gas stream from the patient's surgical cavity. The method is to measure multiple gas species in the gas stream from the surgical cavity and the gas species measured in the gas stream from the surgical cavity are present and / or their desired range respectively. Includes determining if it is within. The method is such that when one or more gas species of multiple gas species are outside their respective desired ranges, the composition of the gas species in the surgical cavity is within each desired range. Includes addition to the surgical cavity. [Selection diagram] Fig. 1
