1. A device for determining information relating to an adherence of a patient having a respiratory disorder, comprising:
a fluid channel configured to be in fluid communication with a medical gas source at a first end and with a patient interface at a second end,
a sensor arrangement having at least a first sensor for measuring a value of a first flow parameter in said channel and a second sensor for measuring a value of a second flow parameter in said channel, and
a control unit in communication with the first sensor and the second sensor, wherein the control unit is configured to determine a flow direction of a medical gas in the channel based on a received measurement of the first sensor and/or second sensor and to determine the information based on the determined flow direction, wherein the first sensor and the second sensor are spaced apart from each other along a longitudinal axis of the channel and are arranged at opposing ends of the channel, wherein the device is configured such that either end of the channel is configured to be coupled to the medical gas source or the patient interface, wherein the determined information indicates a coupling orientation of the device and wherein the control unit is configured to select a particular sensor based on the coupling orientation and the relative position of the particular sensor to perform a measurement of a flow characteristic at a downstream end of the channel.
