System and method for controlling gas composition in surgical cavity during endoscopic surgery

摘要

A method for controlling a gas composition in a surgical cavity during endoscopic surgical procedure involves monitoring a plurality of gas species in a gas stream from a surgical cavity of a patient.The method includes measuring a plurality of gas species in a gas stream from a surgical cavity and determining whether each of the gas species measured in the gas stream from the surgical cavity is present and / or within each desired range.The method includes adding the gas to the surgical cavity to allow the composition of the gas species in the surgical cavity to reach within a desired range if one or more gas species of a plurality of gas species are outside the desired range.Diagram
