1. A patient monitoring system for a sedation and/or analgesia procedure, comprising:
- a first patient health monitor device adapted so as to be coupled to a patient and so as to generate a first signal reflecting a first parameter of a physiological condition of the patient;
a second patient health monitor device adapted so as to be coupled to the patient and so as to generate a second signal reflecting a second parameter of a physiological condition of the patient, wherein said first parameter and said second parameter are interrelated such that said first and said second signal are indicative of a single patient condition associated with said sedation and/or analgesia procedure;
an electronic controller accessing safety parameters for each of said first and second physiological conditions operatively connected to said first and second patient health monitor devices, wherein the electronic controller compares said first and second parameters with said safety parameters so as to initiate a response upon detection of undesirable signals from both of said first and second patient health monitor devices so as to facilitate conservative application of sedative or analgesic drug delivery and/or other suitable effectors, wherein conservative application comprises maintenance or decrease of sedative or analgesic drug delivery, and wherein if the comparison of said first or second parameter with said safety parameters is inconclusive, the electronic controller provides normal system functionality without alerting clinicians while determining whether one patient health monitor device can confirm a potential condition indicated by the other patient health monitor device.

Abstract
The present invention comprises a system that incorporates the natural relationships of patient parameters into a medical monitoring system in order to increase monitoring specificity by reducing false positive alarms resulting from spurious data and inconclusive data. The invention also comprises a system that incorporates the natural relationships of patient parameters in order to use the data obtained from those parameters to non-invasively monitor a patient parameter that typically precludes direct monitoring.

5. A method for employing sensor fusion in a sedation and analgesia system, comprising the following steps:
-
providing at least one patient monitor corresponding to a first patient parameter and at least one patient monitor corresponding to a second patient parameter, wherein said parameters are interrelated and each of said monitors provide data indicative of a single patient condition associated with use of said sedation and/or analgesia system; monitoring at least two of said interrelated patient parameters; ascertaining whether any of said data is indicative of a negative patient episode; if any of said data is indicative of a negative patient episode, determining whether there is agreement between each monitor, or if any of said data is inconclusive, providing normal system functionality without alerting clinicians while determining whether one monitor can confirm a potential condition indicated by at least one other monitor; and initiating a suitable procedure in response to said data indicative of a negative patient episode or confirmed potential condition so as to facilitate conservative application of sedative or analgesic drug delivery and/or other suitable effectors, wherein conservative application comprises maintenance or decrease of sedative or analgesic drug delivery. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13)

14. A method for employing sensor fusion in a drug delivery system during delivery of a sedative and/or analgesic drug, comprising the following steps:
-
providing at least one patient monitor corresponding to a first patient parameter and at least one patient monitor corresponding to a second patient parameter, wherein said parameters are interrelated and each of said monitors provide data; monitoring at least two of said interrelated patient parameters, ascertaining whether the data from any of said monitors is conclusive of a potentially critical condition; if data is inconclusive, providing normal system functionality without alerting clinicians while analyzing the data from said first and second patient parameters to determine whether one monitor can confirm the potentially critical condition indicated by at least one other monitor; and if data is conclusive of a potentially critical condition, alerting clinicians to the detected data and initiating a suitable automated or semi-automated procedure desirable to place the patient into a safe state. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
