Wye fitting: The Wye fitting attaches to the medical airline connection within the office and/or operating room that is typically located at the wall or at a drop down from the ceiling. It branches the medical airline to the Pol-O.R. Bear vest and to the anesthesiologist's station. Wye fittings must be used so that medical air is available to the anesthesiologist's station at all times. The preferred medical coupling type must be specified, such as Ohmeda, Chemtron, Puritan, DISS, etc. (view fittings)

Medical airline tether: These yellow color-coded tethers connect the user from the Wye fitting to the regulator that is provided with the cooling vest. In the case of a multi-user system, the medical airline tether attaches to the multi-user manifold (see below). Tether lengths vary based on the location of the medical airline connection in the room. The preferred medical coupling type must be specified, such as Ohmeda, Chemtron, Puritan, DISS, etc. (view fittings) The following standard tether lengths are recommended:

• 15' for wall mounted medical air couplings
• 8' for ceiling drop down medical air couplings
• 5' for under table pedestal mount
• Other; Texan Corporation can supply alternate tether lengths upon request at additional cost
• Pol-O.R. Bear Cooling Vest: Includes vest and regulator
