This thesis presents the results of an investigation into the absorption of methoxyflurane by conductive rubber and polyethylene anesthetic hose. Previous studies are reviewed and theoretical considerations governing the diffusion process are discussed.

Diffusion coefficients are calculated for commercially available hose materials using different anesthetic concentrations and oxygen flow rates.

Data obtained is compared with the results of previous investigations (primarily concerned with sorption into rubber hose) and similar results are presented for polyethylene hose.

Graphical data is used to demonstrate the effect of hose material on inspired anesthetic concentration.

The advantage of disposable conductive polyethylene hose over reusable rubber hose is shown.
