    摘要： An apparatus for detecting an irregular state in a non-invasive pulse oximeter system comprises an oxygen saturation sensing probe generating spectrophotometric signals and an oxygen saturation computing section for deriving the 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 signal 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 fulfil this criterion. The presence of the irregular state is detected if the actual criterions fulfil the criterion.
