Current practice in our OR is anesthesia fills their machines with the gas and then the bottle is returned to the ADC to ensure these are locked up. The problem, however, is the bottles being returned are partial (open) bottles. Thinking about maintaining integrity, would there be any concerns with these partial bottles remaining in the ADCs? Outside of keeping these locked up, the only other option would be to top off the reservoir and then waste the remaining amount. We want to ensure we can speak to the integrity if anything is mentioned during a survey.

If we keep the partial bottles, do we treat them as multi-dose containers and give them a 28-day expiration?

How do you handle this in your ORs? Any and all feedback is appreciated.
