    摘要： An electrochemical sensor (40) is provided, the sensor comprising a working electrode (44); a counter electrode (46); and an ionic liquid medium extending between the working electrode and the counter electrode, the ionic liquid medium comprising an ionic liquid retained in a support material. The ionic liquid may comprise a cation selected from 1-alkyl-3-methylimidazolium ([CnMIM]), N-alkytpyridinium, tetraalkylammonium or tetraalkylphosphonium cations and an anion selected from hexafluorophosphate [PF6]; tetrafluoroborate [BF4]; trifluoromethylsulfonate [CF3SO3]; bis[(trifluoromethyl) sulfonyl]amide [(CF3SO2)2N]; trifluoroethanoate [CF3CO2]; acetate [CH3CO2]; nitrate, and halides, including fluoride [F]1 chloride [Cl], and bromide [Br]. The sensor is particularly useful in the detection of gaseous components in the exhaled breath of a subject and for use in monitoring the lung function of the subject, for example to identify the onset of asthma and/or COPD.

    摘要： A method for the determination of the carbon dioxide content of an exhaled gas stream is provided, the method comprising measuring the water vapour content of the exhaled gas stream,- and determining the concentration of carbon dioxide in the exhaled gas stream from the measured water vapour content. A particular method comprises causing the gas stream to impinge on a sensing element comprising a working electrode and a counter electrode; applying an electric potential across the working electrode and counter electrode; measuring the current flowing between the working electrode and counter electrode as a result of the applied potential; and determining from the measured current flow an indication of the concentration of the water vapour in the gas stream. A sensor is also described.

    摘要： An apparatus for monitoring the respiration of a subject, the apparatus comprises means for detecting the concentration of each of oxygen, carbon dioxide and nitric oxide in an inspired and/or exhaled gaseous stream of a subject; and a display for displaying the concentration of each of oxygen, carbon dioxide and nitric oxide. A method for monitoring the respiration of a subject comprises analysing the composition of the inspired and/or exhaled gas of the subject and determing the concentration of carbon dioxide, oxygen and nitric oxide in the gas; and displaying the results of the analysis on a display to provide an indication of the respiratory state of the subject. A method of determining the extent of resuscitation of a patient comprises measuring the concentration of carbon dioxide, oxygen and nitric oxide in the inspired gas stream and/or exhaled gas stream of the subject.
