Abstract
A method for managing pressure in a breathing assistance system configured to provide breathing assistance to a patient via a patient connection system is provided. The method may include receiving one or more first pressure sensor signals from a first pressure sensor, and analyzing the one or more first pressure sensor signals. Based at least on the analysis of the one or more first pressure sensor signals, either the first pressure sensor or the second pressure sensor may be selected for use in controlling the breathing assistance provided to the patient, and the breathing assistance provided to the patient may be controlled based at least on signals from the selected pressure sensor.

27. A method for controlling a breathing assistance system configured to provide breathing assistance to a patient, comprising:
-
automatically determining whether a proximal pressure line having an associated proximal pressure sensor is connected to the breathing assistance system; and automatically determining whether or not to use signals from the proximal pressure sensor for controlling a subsequent operation of the breathing assistance system based on the determination of whether the proximal pressure line is connected to the breathing assistance system. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41)

42. A method for controlling a breathing assistance system configured to provide breathing assistance to a patient, comprising:
-
automatically determining whether a proximal pressure line having an associated proximal pressure sensor is connected to the breathing assistance system; automatically determining to allow or disallow at least one particular breathing assistance mode or setting based on whether the proximal pressure line is determined to be connected to the breathing assistance system; and selecting a particular breathing assistance mode or setting based at least on the determination to allow or disallow at least one particular breathing assistance mode or setting; and providing breathing assistance to the patient according to the selected breathing assistance mode or setting. - View Dependent Claims (43, 44, 45)

46. A method for controlling a breathing assistance system configured to provide breathing assistance to a patient, comprising:
-
automatically identifying that a first pressure sensor of the breathing assistance system is currently usable; and in response to determining that the first pressure sensor is not currently usable, automatically switching from a first, currently selected breathing assistance mode to a different, second breathing assistance mode predefined for use with signals from a second pressure sensor; and automatically implementing the second breathing mode and controlling at least one parameter of the breathing assistance system based on signals from the second pressure sensor.
