  • Flow restrictor for measuring respiratory parameters
    Patent number: 6224560
    Abstract: A flow restrictor is applied to a respiration-channeling device such as a tracheostomy tube, a mouthpiece, or a face mask. The flow restrictor creates a pressure differential which varies with volume flow rate. A pressure reading is taken on either side of the flow restrictor in the respiration-channeling device and from this, a volume flow rate is determined. A data acquisition device is used to derive further pulmonary function parameters from the volume flow rate.
