The LAVC-2000-D offers the same control over the patient as the LAVC-2000 but adds the ability to passively breathe with a 30L or 15L bag. The absorber canister is mounted on the side to allow the bag to hang properly and with the switching of a single hose you can switch between the bellows and the bag. This allows for another level of control and safety. Optional Equipment Oxygen Supply Hose with or without quick-connect (must specify connection type and length) Single Adjustable Stainless Steel Monitor Shelf Double Adjustable Stainless Steel Monitor Shelf Scavenger Interface Valve (specify type) E-cylinder mounting bracket for portable use Custom options and specifications available. The system can be modified to meet any need or special use. Please contact us for more information.
