<p>An apparatus for non-invasive measurement of oxygen saturation for connection to a sensor (1,43,49) comprises a convertor for converting the intensity of the received electromagnetic waves into electrical signals, a comparator for comparing the electrical signals with sets of predefined signals representative of certain places of application at the human body or representative of certain tissue characteristics and for selecting the set comprising most common characteristics with the electrical signals. Correction means correct the electrical signals in dependency of selected set. Further, a processor (47) calculates the oxygen saturation from the corrected electrical signals. <IMAGE></p> |
