To use the Exit bag with an inert gas, one needs to connect the gas cylinder to the bag. Plastic tubing (eg. standard 2-metre oxygen tubing with soft connectors as used with home nebulisers) is generally available from pharmacies. The tubing is tightly-fitted to the Max Dog regulator outlet. Tape the other end firmly to the inside wall of the Exit Bag .
Note: The short film ‘Do it Yourself with Betty’ details how to attach the gas hose to the bag. Betty used ‘Balloon Time’ Helium in this film but the principal is the same for nitrogen (or argon).
Adjust the elastic on the Exit bag so it is a firm, but not tight, fit around the neck, then position the bag on the forehead.
