|Official Title:||Effectiveness of Carbon Filters to Reduce the Anesthetic Gas Concentration in an Anesthetized Patient|
|Study Start Date :||July 2012|
|Estimated Primary Completion Date :||June 2013|
|Estimated Study Completion Date :||June 2013|
Experimental: Treatment (filter in circuit)
After baseline use of volatile anesthetic, this group will have carbon filter placed in-line.
Device: In-line Carbon filter (Vapor-Clean)
Carbon filter placed in anesthesia breathing circuit.
Other Name: Vapor-Clean Brand Carbon Filter (Dynasthetics, LLC)
No Intervention: No Intervention Control
After baseline use of volatile anesthetic, this group will NOT have carbon filter placed in-line.
- Time to reduce Concentration of Volatile Anesthetic to <5ppm [ Time Frame: every two minutes after filter applied until concentration is <5ppm or 30 minutes ]At regular intervals (2 minutes) after application of the filters, the concentration of the volatile anesthetic will be measured. Primary outcome value will be the time to reduce breathing circuit volatile anesthetic concentration to <5ppm. If at 30 min the concentration is not <5ppm, then collection will be stopped.
