Abstract

Physico-chemical parameters, such as pH, pO.sub.2, pCO.sub.2, % O.sub.2, sat, etc., are determined with the use of a sensitive medium, such as a chromophore, having at least one optical property the profile of the spectrum whereof over a predetermined wavelength spectrum of optical radiation varies as a function of the parameter to be determined. The profile of the spectrum is analysed, for example by means of polychromatic sensor means acting on the medium's spectrum, which is preferably substantially continuous, so as to enable the analysis to be carried out with the aid of a profile-recognition function by typical pattern-recognition operations. The determination is thus rendered largely independent of numerous perturbing factors such as those resulting from the use of partially disposable monitoring units, thus eliminating the need for calibration steps.
