A sensor device for EIT imaging comprises an electrode array for measuring an impedance distribution, with at least one sensor for determining spatial orientation of the electrode array coupled to the electrode array. EIT imaging instrument is connectable to a sensor for determining spatial orientation of a test person, and optionally in addition connectable to a sensor for gathering information on electrical and/or acoustic activity and/or a sensor for gathering information on dilation. A computing device is connected or integrated for adjusting impedance data based on spatial data, which spatial data describe the spatial orientation of a test subject. An EIT imaging method for measuring an impedance distribution and adjusting said measured impedance distribution comprises measuring impedance distribution by using an impedance distribution measuring device comprising an electrode array, and transforming the measured impedance distribution into EIT images.

An observation unit (OU) and auxiliary observation unit (AOU) sensor are calibrated in relation to an ambient environment. The OU sensor and the AOU sensor are calibrated in relation to an observational subject. Monitoring parameters are established for the calibrated sensors using a receiving unit (RU). Monitoring types are activated using the RU. Data is gathered from the OU sensor and the AOU sensor. A determination is made that the gathered data exceeds the established monitoring parameters. One or more alerts are generated based on the determination.

Presented are concepts for monitoring cardio-respiratory function of a patient. One such concept comprises detecting light or sound from the sublingual vasculature using a sublingual sensor unit adapted to be positioned at a sublingual vasculature of the patient's tongue and to generate a sensor output signal based on the detected light or sound. A processing unit adapted to receive at least one of the sensor unit output signal, wherein the sensor unit and the processing unit are arranged to analyze the venous component in the sensor output signal. An output signal from the sublingual sensor may then be used to provide information on cardio-respiratory parameters like respiration rate and respiration rate variability, for example.

A system screens, diagnoses, or monitors sleep disordered breathing of a patient. The system may include a nasal cannula, a conduit connected to the nasal cannula at a first end, an adaptor configured to receive a second end of the conduit and/or a portable computing device. The adaptor may be configured to position the second end of the conduit in proximity with a microphone of the portable computing device. Optionally, a processor may generate an indicator to guide placement of the adaptor for use. Such positioning may, in use, permit the microphone to generate a patient breathing sound signal via the adaptor for processor(s) of the device.
