  • Patent number: 6192876
    Abstract: An apparatus for and a method of ensuring the fit of a face mask to the face of a patient, the apparatus including a face mask having an inlet through which gas can be inhaled and a sensor for measuring the flow rate of gas drawn through the inlet of the face mask. The fit of the face mask is determined by monitoring the flow rate of gas drawn through the inlet of the face mask upon inhalation by a patient. The face mask is considered to satisfactorily fit the patient when a substantially regular inhalation waveform is achieved.
