Waste Anesthetic Gas Disposal Methods

    I have a facility that does not have in wall suction.  They sent the following request:  Currently we have one anesthesia machine with passive evacuation and I was first told that as long as the OR’s have a wall to the outside we can stay with passive evacuation. Passive evac is basically a closed tube from the machine to the outside with no power assistance. However, now I am being told that we must have some kind of active evacuation and I’m looking for what device or method can be used in the two OR’s to provide the evacuation without having wall suction.

    Both of our anesthesia machines will be GE Aestiva 5 machines, but we want the flexibility in the future to have newer machines (which I am told require some kind of active assisted evacuation).

    Wanted to know if anyone has a Venturi system and can make any system recommendations??  Thanks  David Meek

    David, do they have a non-medical air source?  A venturi will need a power gas (air is perfect).  If so, when contact me and I can get you details on the european venturi outlets.  If not, then there are some other options but it gets complicated, so we would need to talk in more detail.

    5.1.3.8.1.7  If WAGD is produced by a venturi, the following shall apply: 

    (1) The venturi shall not be user-adjustable (i.e., require the use of special tools).

     Yes to my knowledge GE is changing all their anesthesia machines to only except active waste gas systems.  If they bought another brand they still make passive systems. 

     You could consider individual small vacuum pumps, example Gomco for each machine.

    Thanks for everyone's input, customer is looking for possible air source per Mark's recommendation and also now looking for a possible location for a small vac pump.  Mark I will let you know if they head the Venturi direction.
