Abstract
A method and system for removal of nitrous oxide and volatile halocarbon gas components from waste anesthetic gases using a low-flow scavenging or reclamation system preferably including an intelligent waste anesthetic gas collection unit fluidly coupled between each individual anesthetic machine and the waste gas evacuation manifold. Through a system including a collection chamber, a pressure detector, and a exhaust valve which is actuated based on the detected pressure in the collection chamber, the waste anesthetic gas collection unit allows flow to the waste suction manifold only in the presence of waste gas and interrupts all flow into the suction manifold when no waste gas is present.
