Abstract
Oppfinnelsen vedrører en fremgangsmåte og et apparat for å overvåke en sedert pasient, særlig for å tilveiebringe utgangssignaler som angir tilstand av våkenhet og smerte hos pasienten. Fremgangsmåten omfatter trinnene å tilveiebringe et utledningsevnesignal målt ved et område av pasientens hud, å gjenkjenne en aktivitet i et høyfrekvensområde av nevnte målesignal, og å etablere en tilstand av smerte hos pasienten ved gjenkjennelse av nevnte aktivitet. Gjenkjennelsen kan utføres ved å analysere utgangen fra et høypassfilter eller ved å analysere resultatene av utgangene av to ulike lavpassfiltre, etterfulgt av en logisk operasjon. Analysene kan enten utføres ved en frekvensspektermetode, ved bruk av amplituden for et spektertyngdepunkt som indikasjon på en gjenkjent aktivitet, eller ved en tidsdomenemetode, der antall gyldige topper og bunner i hudledningsevnesignalet telles gjennom måleintervallet.The invention relates to a method and apparatus for monitoring a sed patient, in particular to provide output signals indicating the state of alertness and pain in the patient. The method comprises the steps of providing a conductivity signal measured at a region of the patient's skin, recognizing an activity in a high frequency range of said measurement signal, and establishing a state of pain in the patient by recognizing said activity. The recognition can be performed by analyzing the output of a high pass filter or by analyzing the results of the outputs of two different low pass filters, followed by a logical operation. The assays can either be performed by a frequency spectrum method, using the amplitude of a spectrum center of gravity as an indication of a recognized activity, or by a time domain method where the number of valid peaks and bottoms in the skin conductivity signal is counted through the measurement range.
