Percentage of cases with mean fresh gas flow (FGF) equal to, or less than 3L/min, during administration of halogenated hydrocarbons and/or nitrous oxide.
This measure considers Fresh Gas Flow (FGF) during administration of halogenated hydrocarbons and/or nitrous oxide, as an indirect measure of anesthetic gas waste. For a given case, this measure will include the maintenance period of anesthesia, defined as the time between placement of an endotracheal tube or supraglottic airway and removal of the endotracheal tube or supraglottic airway.
Halogenated agents and nitrous oxide leaking or vented into the atmosphere are environmental pollutants. Reducing fresh gas flows can reduce cost of anesthesia without compromising patient care.
Mean FGF equal to, or less than 3L/minute when inspired halogenated hydrocarbons is >0.2%, or nitrous oxide FGF >0.2L/min, during the maintenance period of anesthesia.
Measure Start:
Measure End:
All providers signed in for at least 30 minutes during the time when halogenated agent or nitrous oxide are documented.
Method for determining Responsible Provider:
All providers signed in while patients are administered halogenated hydrocarbons, and/or nitrous oxide, for more than, or equal to, 30 minutes from placement of the airway device to removal of the airway device. See ‘Other Measure Build Details’ section for algorithm for determining measure start and end times.
