Abstract
A method and an apparatus enable detection of an irregular state in a non-invasive pulse oximeter system. The system comprises an oxygen saturation sensing probe for generating spectrophotometric signals and an oxygen saturation computing section for deriving arterial hemoglobin oxygen saturation from the spectrophotometric signals. Irregular states of the system are detected by pre-defining at least one criterion for distinguishing between spectrophotometric signals indicative of the normal state of the system and spectrophotometric signals generated by the pulse oximeter system when a predetermined non-physiological event occurs. Then it is judged whether the actual spectrophotometric signals fulfill this criterion. The presence of the irregular state is detected if the actual criterion fulfill the criterion.
