1. An intelligent brain rescue instrument for identifying, monitoring, and guiding the application of brain therapies to patients with evolving brain injuries, comprising: I) input means for acquiring a set of a multiple number of signals each indicative of a different biochemical or biophysical parameter of the patient, said set of signals including a multiple number of signals selected from: (a) an EEG signal; (b) an ECG signal; (c) a signal indicative of brain tissue impedance of the patient; (d) signal or signals indicative of the temperature of the patient; (e) signals indicative of the arterial blood pressure and/or arterial oxygen saturation, of the patient; (f) a signal indicative of intracranial pressure; (g) a signal or signals indicative of any of cerebral blood flow, cerebral blood volume, cerebral oxygenation, or cerebral metabolite measures; (h) a signal or signals indicative of systemic glucose concentration and/or central glucose concentration; (i) a signal or signals indicative of systemic lactate concentration and/or central lactate concentration; (j) a signal indicative of cerebrovascular status; (k) a signal indicative of cerebral cytochrome levels; (l) a signal indicative of the patient's heart rate; (m) a signal indicative of central cytotoxic activity; (n) a signal or signals indicative of movement or muscle activity; (o) a signal or signals indicative of any other biochemical or biophysical parameter useful as indicative of the current or as predictive of the future brain state of the patient; and II) computing means configured to continuously sample and process each of the acquired signals, and display to a user on a monitor information a selected subset of the acquired parameters, said selected subset of parameters which is displayed being selected either by system software, including signal analysis modules arranged to perform initial signal processing and analysis and brain rescue task modules arranged to process data from the signal analysis modules and embodying expert analytical rules, as parameters having values indicative or predictive at any time of actual or potential future deterioration of the brain state of the patient, with said parameters being displayed against a scale or scales or in a way which highlights to a clinician any variations of the parameters indicative or predictive of the deterioration of the brain state of the patient to enable identification, monitoring, and guiding of the application of brain therapies to a patient with an evolving brain injury, or alternatively being override selected at any time by the user.
