Patient monitoring during drug administration
First Claim
1. A method for monitoring a patient, the method comprising the steps of:
- administering at least one drug to a patient;
maintaining drug administration data that identifies the at least one drug administered in the administering step;
obtaining physiological signal data from the patient;
based on the physiological signal data, determining at least one state index indicative of a clinical state of the patient; and
controlling the determining step in dependence on the drug administration data, thereby to produce values for the at least one state index, which remain substantially consistent regardless of the at least one drug administered to the patient.

Abstract
The invention relates to a method and apparatus for monitoring a patient during drug administration. In the monitoring process, at least one state index indicative of the clinical state of the patient is determined based on physiological signal data obtained from the patient. In order to eliminate inconsistencies caused by varying drug combinations in the at least one state index, drug administration data is maintained, which identifies the drug(s) administered to the patient, and the determination of the at least one state index is controlled in dependence on the drug administration data, thereby to produce values for the at least one state index, which remain substantially consistent regardless of the particular combination of the drugs administered to the patient.

13. An apparatus for monitoring a patient, the apparatus comprising:
-
means for receiving drug administration data that identifies at least one drug administered to a patient;
monitoring means for determining, based on physiological signal data obtained from the patient, at least one state index indicative of a clinical state of the patient; and
control means for controlling the monitoring means in dependence on the drug administration data, thereby to produce values for the at least one state index, which remain substantially consistent regardless of the at least one drug administered to the patient. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. An apparatus for monitoring a patient, the apparatus comprising:
-
a first controller configured to receive drug administration data that identifies at least one drug administered to a patient;
a computing unit configured to determine, based on physiological signal data obtained from the patient, at least one state index indicative of a clinical state of the patient; and
a third controller configured to control the computing unit in dependence on the drug administration data, thereby to produce values for the at least one state index, which remain substantially consistent regardless of the at least one drug administered to the patient.

26. A computer program product for an apparatus monitoring a patient, the computer product comprising:
-
a first program code portion configured to receive drug administration data which identifies at least one drug administered to a patient; and
a second program code portion configured to control a monitoring process adapted to calculate at least one state index indicative of a clinical state of the patient, wherein the second program code portion is configured to control the monitoring process in dependence on the drug administration data thereby to eliminate drug-dependent inconsistencies in the at least one state index.
