Embodiments provide an oxygen supply device having multiple operational states including a first state and a second state. In the first state, the oxygen supply device is controllable to a local control instruction such that the oxygen supply device can be operated by a user physically located within a proximity of the oxygen supply device. In the second state, the oxygen supply device is only controllable to a remote-control instruction such that the oxygen supply device can be operated by a user remote to the oxygen supply device. For example, the user can be located in an office remote to a location of the oxygen supply device, which, for example, may be placed at a patient’s home. In the second state, the user is enabled to control the oxygen supply device from a device associated with the user in the remote location.

There is provided a method of detecting a fault in a breathing system. The method comprises the steps of (a) taking a series of measurements of a first parameter of the breathing system; and (b) setting a fault boundary for the first parameter, the fault boundary being dependent on a plurality of the measurements of the first parameter. The method further includes at least one update procedure comprising the steps of (c) taking one or more further measurements of the first parameter; and (d) updating the fault boundary, the updated fault boundary being dependent on an updated set of measurements of the first parameter, the updated set of measurements of the first parameter including at least one of the further measurements of the first parameter.
