Abstract
A system that enables remote adjustment of oxygen flow from an oxygen source includes a gas source device fluidly coupled to a gas source, a remote delivery device with an outlet for providing gas to a user and an inlet fluidly coupled to an outlet of the gas source device, wherein the gas source device has a control system. The control system determines a current control setting of the remote delivery device based on pneumatic feedback from the remote delivery device and modifies a pressure of gas flowing from the gas source device to the remote delivery device based on the current control setting of the remote delivery device, so that a target flow volume of supply gas associated with the current control setting is delivered to the inlet.
