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.

A method for automatically detecting a clinically relevant leak and/or inadequate closure following a medical procedure, in a hollow organ residing in the interior volume of a body cavity. The test method includes the steps of: injecting, via an adapted injection element, a specific test gas or a gas mixture containing at least one test gas, into the organ, analyzing the gas mixture and measuring the test gas concentration in the interior volume of the body cavity via an adapted detection element and at least during a measurement window, evaluating the likelihood of the presence of a leak and its degree of severity, by comparing stored data and real-time data with each other. The pressure difference between the interior of the hollow organ(s) and the interior volume of the body cavity is controlled or mastered at least at a given moment during at least one measurement window.

The disclosed embodiments are directed to secondary methods of communicating with a drug delivery device when the primary method is unavailable. Secondary methods include the use of a pattern of taps on the housing of the drug delivery device to convey authentication information and commands to the drug delivery device. Feedback confirming the interpretation of the pattern of taps may be provided to the user via a vibration, sound, or blinking lights.

A ventilator including a housing; a gas inlet port disposed in the housing and adapted to be coupled to a gas source to receive a flow of gas; a valve assembly coupled with the gas inlet port for controlling flow of gas from the gas inlet port to a gas outlet port disposed in the housing and adapted for being coupled to a patient interface to fluidly couple the gas outlet port to the airway of a patient; a controller module disposed in the housing, the controller module comprising a controller operatively coupled with the valve assembly to control operation of the valve assembly; an airway pressure sensor positioned between the valve assembly and the patient interface to measure air flow output into flowing into the airway of the patient; wherein the pressure sensor is operatively connected to the controller module to control the operation of the valve assembly in response to changes in air flow output measured by the airway pressure sensor during use.
