Method and device for the non-invasive monitoring and identification of drug effects and interactions

A method for use in detecting and monitoring effects experienced by a subject taking a first drug, drug A, and at least one other substance, substance B, the method comprising: (a) obtaining a plurality of measured values of a physiological characteristic of the subject over a time period; (b) comparing the measured values to a predefined signature, the drug A signature, associated with the first drug, and thereby calculating a measure, Adiff, of the difference between the measured values and the drug A signature; (c) comparing the measured values to a predefined signature, the substance B signature, associated with the at least one other substance, and thereby calculating a measure, Bdiff, of the difference between the measured values and the substance B signature; (d) comparing the measured values to a predefined signature, the DO signature, associated with a desired physiological state of the subject, and thereby calculating a measure, DOdiff, of the difference between the measured values and the DO signature; and (e) combining Adiff and DOdiff to produce an output

System and method for analysis of the upper airway and a respiratory pressure support system

A system for analysis of the upper airway has a sensor arrangement with at least two sensor positions provided along a flow path leading to the mouth and/or nose of a user (4). A relation is derived between sensor signals at the two locations, and this is interpreted to detect at least the presence of upper airway obstructions, and preferably also the location and/or extent of such obstructions. The system is adapted to distinguish between inhalation and exhalation using the acoustic arrangement signals at the first and second locations

System and method for determining a risk level of a respiratory attack

A system determines a risk level of a respiratory attack of a user of the system. The system comprises part of a network of systems, and it reports information to, and receives information from, the network. The system comprises a local activity monitoring device for tracking the physical activity level of the user. Location information and activity levels in respect of other users of the network of systems are received, relating to when they have suffered a respiratory attack. A warning can then be given to the user which takes account of the location of the user and the activity level or planned activity level of the user, and the received location information and activity levels in respect of other users.<br/
