Abstract
Systems and methods of controlling fluid flow of an inhalant anesthetic to expedite patient recovery are provided such that nitrous oxide flow and oxygen flow over different durations are output to a patient mask. In one exemplary embodiment, a method performed by a controller in an inhalant anesthetic system that outputs a nitrous oxide flow and an oxygen flow over different durations for output to a patient mask comprises sending, to a nitrous oxide flow control mechanism, an indication to enable the nitrous oxide flow for a first predetermined duration that corresponds to a certain amount of nitrous oxide. Further, the method includes sending, by the controller, to the oxygen flow control mechanism, an indication to enable the oxygen flow for a second predetermined duration that corresponds to a certain amount of oxygen.
