  • Oxygen mixing in a blower-based ventilator
    Patent number: 6123074
    Abstract: An oxygen mixing arrangement for or in a pressure support ventilator, in which a modular oxygen-providing assembly is selectively insertable into a greater respiration apparatus. Mixing accuracy and controllability is maintained by using gas supplies that have a wide range of pressures. Further, oxygen leakage is minimized by connecting the modular oxygen-providing assembly at a point of the respiration circuit of the greater respiration apparatus that is downstream from a valving arrangement normally used for venting patient exhaust flow and for controlling system pressure by venting excess gas flow to the ambient atmosphere.
    Type: Grant
    Filed: July 24, 1997
    Date of Patent: September 26, 2000
    Assignee: Respironics, Inc.
