Hi there I am back from Ontario and British Colombia and working at South Health Campus in Calgary Alberta. I wonder if someone can help me set-up our AESTIVA Passive anesthesia scavenging system. We actually have a new AGSS system in the hospital that we currently use in OR just recently we have are getting a request to set-up an AESTIVA anesthesia unit in ICU Isolation unit and we don't have AGSS currently installed on ICU unit, as being not requested during the planning of the hospital. So we will have to make do with the PASSIVE system. Can someone give me an insight of how can we be able to set it up? I know some of you will say the Suction unit but need some info on how can we set-up it out other than suction?
