Abstract

A breathing system includes a pressurized fluid supply, a downstream breathing device, and a fluid regulator comprising. The fluid regulator includes an inlet in fluid connection with the fluid supply, and an outlet in fluid connection with a downstream breathing device. The fluid supply supplies fluid at a first pressure to the inlet, and the fluid is at a second pressure at the outlet that is lower than the first pressure. The fluid regulator also includes a boost tube disposed within an outlet portion of the fluid regulator. The boost tube includes a body defining a length and a plurality of apertures extending through the length of the body and configured to reduce the turbulence of the fluid flowing from the outlet to the downstream breathing device.
