Abstract
The invention pertains to a method for determining the level of analgesia of a sedated individual, to the use of an apparatus for determining the level of analgesia of a sedated individual (so called “pain monitor”), as well as the use of an evoked pain-specific reflex response of a sedated individual for determining the level of analgesia of a sedated individual.

10. A method for determining the level of analgesia of a sedated or anesthetized individual comprising the steps of:
-
providing an apparatus, wherein the apparatus comprises; a stimulation unit for generating a stimulation signal for pain-specific reflex, a measurement unit for recording a pain-specific reflex signal in response to the stimulation signal, and a control unit for adapting the intensity of the stimulation signal, and wherein the control unit decreases the intensity of the stimulation signal when the pain-specific reflex signal that is caused by the stimulation signal is above an index value of the reflex response, and the control unit increases the intensity of the stimulation signal when the pain specific reflex response caused by the stimulation signal is below a predetermined index value of the reflex response, generating a stimulation signal for pain-specific reflex with the stimulation unit, recording a pain-specific reflex signal in response to the stimulation signal with the measurement unit, and adapting the intensity of the stimulation signal with the control unit, and determining the level of analgesia using the recorded pain-specific reflex signal. - View Dependent Claims (11)

12. A method for determining a level of analgesia of a sedated individual, comprising the following steps:
-
generating a reflex stimulation signal for deploying a pain-specific reflex response, adapting the intensity of the reflex stimulation signal based on a feedback loop, determining a calculated stimulation signal intensity, triggering a reflex response signal of a predetermined index value, and determining the level of analgesia of the sedated individual using the calculated stimulation signal intensity. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
