Surgical method for performing an open surgical site surgery

A surgical method for performing an open surgical site surgery, comprising:

• making an incision in a patient;
• opening the incision in order to create an open surgical site in the patient;
• receiving a gas from a source;
• humidifying and warming the gas received from the source;
• flowing the humidified and warmed gas through a non-porous gas delivery mechanism comprising a cup-shaped structure that defines a chamber, the cup-shaped structure having a base, a rim, and a cup-shaped sidewall connecting the base to the rim, wherein the base defines an inlet connecting to an inlet passage of the non-porous gas delivery mechanism, the rim defines an outlet positioned opposite the inlet, and the base has a smaller diameter than the rim, wherein as the humidified and warmed gas flows from the inlet to the outlet of the cup-shaped structure, the humidified and warmed gas is successively reflected off a plurality of non-porous surfaces within the non-porous gas delivery mechanism to create a flow, wherein at least one of the plurality of non-porous surfaces comprises the cup-shaped sidewall, and wherein a second of the plurality of non-porous surfaces is positioned within the chamber defined by the cup-shaped structure and oriented such that it is in a path of the humidified and warmed gas reflected to or from the cup-shaped sidewall of the non-porous gas delivery mechanism;
• delivering the flow of the humidified and warmed gas adjacent to or into the open surgical site via the outlet;
• receiving condensation created by the humidified and warmed gas;
• and
• directing at least a portion of the condensation through one or more openings in at least one of the plurality of non-porous surfaces.
