Abstract
An apparatus for delivering a breathing gas to a patient includes a display, a storage device programmed to hold different purge hole leak profiles for a variety of mask types, and a selection mechanism for selecting one of the profiles so that accurate values of tidal volume, excess leak and peak flow may be calculated and shown on the display. The displayed excess leak value can be used to correct the fit of the mask.
