Oxygen mixing in a blower-based ventilator |
摘要 |
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. |
