摘要： A handheld, small but accurate and reliable device for diagnostic NO measurements using a NO sensor, where the parameters governing the taking of the sample are different from the parameters optimal for the accuracy of said NO sensor I described. By temporarily storing a portion of the exhaled air, and feeding this to the sensor at a flow rate adapted to the NO sensor, the accuracy and sensitivity of a system/method involving NO sensors, in particular electrochemical NO sensors, can be increased. The method for diagnostic NO measurements comprises steps for controlling the inhalation of NO free air, as well as the exhalation, both by built-in means and by audible and/or visual feedback to the patient.

摘要： A method for testing the measuring accuracy of a measuring device (7) for gas measurements, comprising a gas inlet opening (70), comprising the steps; connecting a special reference gas, having a known concentration and having a controlled flow rate and pressure, where the flow rate and the pressure are controlled to be within certain limits, to the gas inlet opening (70); and evaluating the reading in relation to the known concentration of the special reference gas. A control device (1), for use in the method, for controlling the pressure and flow rate of a gas source connected the control device (1) so as to assure a controlled pressure and flow rate at a gas output (17) of the control device (1), which comprises a flow rate controlling element (11) and a pressure controlling element (13) connected between the gas input (10) and the gas output (17).
