First Claim
Patent Images
1. A method for displaying an indicator of a current pain level of a patient being administered an analgesic, the method comprising:
- providing a display device;
measuring a current mean arterial pressure and heart rate of the patient;
deriving the indicator from said measured current mean arterial pressure and heart rate; and
displaying said derived indicator on said display device.

Abstract
A method and system for objectively scoring intra-operative pain during general anaesthesia based on the patient'"'"'s mean arterial pressure and heart rate. The index is used for closed-loop control of the intra-operative analgesia through adjustment of the drug infusion level according to fuzzy logic. It is further displayed along with other components of anaesthesia and important patient data on a monitoring display for presentation to medical staff.

21. A system for displaying a current state of anaesthesia of a patient undergoing surgery, the system comprising:
-
a first subsystem for measuring a current anaesthetic depth in the patient; a second subsystem for monitoring a current level of muscular relaxation in the patient; a third subsystem for deriving an indicator representative of a current pain level of the patient; and a single display device coupled to said first, second, and third subsystems for simultaneously displaying said current anaesthetic depth, said current level of muscular relaxation and said derived indicator. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
