The systems of the present invention provide improved accuracy in monitoring, analysing, detecting, predicting and / or providing alerts and alarms associated with depth of anaesthesia, depth of consciousness, hypnotic state, sedation depth, fatigue or vigilance of a subject, with as few as 3 surface electrodes. The systems incorporate real-time phase, amplitude and frequency analysis of a subject's electro-encephalogram. The systems weight outputs of various types of analyses to produce an integrated analysis or display for precise indication or alert to users of the systems including anaesthetists, nurses and other medical personnel, transport drivers and machine workers. The systems weight the outputs of one or more analysis algorithms including combinations of simultaneous, real-time R&K analysis, AEP spectral analysis-SEF-MF, Bi-coherence analysis, initial wave analysis, auditory response, arousal analysis, body movement analysis, 95% spectral edge analysis and anaesthetic phase and spectral energy variance measurement in association with a subject's state of consciousness.

The invention relates to a method for monitoring a condition of a patient under anesthesia or sedation, whereupon one, two, three or more signals are acquired, and the signal(s) represent(s) cardiovascular and / or combined electrical biopotential on skull activity of the patient. From said signal or signals are derived or calculated at least two parameter values related to a quantity like waveform amplitude, waveform periodicity, waveform morphology, waveform variability, energy, power, signal complexity and frequency content. A predetermined mathematical index for probability of patient comfort is used, in which function said parameters are variables, and successively changing probability index values of said mathematical index is calculated.

A care system and associated methods are provided for alleviating patient pain, anxiety and discomfort associated with medical or surgical procedures, the system comprising: at least one patient health monitor device coupled to a patient and generating a signal reflecting at least one physiological condition of the patient; a drug delivery controller supplying one or more drugs to the patient; a memory device storing a safety data set reflecting parameters of the at least one patient physiological condition; and an electronic controller interconnected between the patient health monitor, the drug delivery controller and the safety data set; wherein said electronic controller manages the application of the drugs in accord with the safety data set. In another aspect of the invention, the care system facilitates a procedural physician's safely and efficaciously providing conscious sedation to a patient by additionally providing a consciousness monitoring-system which monitors the consciousness of the patient and generates a value representing the level of patient consciousness. Methods for alleviating patient pain and anxiety in accordance with the invention comprise connecting a drug delivery device to a patient, such device having a drug delivery controller supplying one or more drugs and being coupled to an electronic controller; attaching at least one patient health monitor device to the patient; accessing a memory device which stores a safety data set reflecting parameters of at least one patient physiological condition; and delivering the drugs to the patient in accord with the safety data set. In further aspects of the invention, the consciousness monitoring system is an automated consciousness monitoring system which includes patient query and response devices. Additional embodiments of the system and methods are directed to alleviating patient pain or discomfort while enabling safe patient controlled drug delivery in correlation with the monitoring of patient health conditions.

The present invention comprises a user interface for systems and methods for sedation and analgesia delivery. The user interface receives input from a user of a sedation and analgesia delivery system and relays information regarding the system, the administration of sedation and analgesia, physiological conditions to the user in a context sensitive manner. The information relayed may be displayed to the user on a touch sensitive screen or multi-layer display device. The display may be segregated geographically or may be color coded on the display device where the geographic location or color of the displayed information relates further information to the user.
