Abstract:
An apparatus for the collection of bioenergetic data indicative of bioenergetic status of a body comprising:a) optical monitoring means comprising detection means adapted to detect light and one or more light sources, the optical monitoring means being arranged and configured such that in use light from the one or more light sources passes through a part of the body of a patient, whereby the light is affected by the light characteristics of the part of the body and modulated by blood flowing within the part of the body, the optical monitoring means producing time-varying signals in response to the light detected by the detection means;b) display means for displaying a trace;c) processing means in signal connection with the optical monitoring means and the display means for processing the time-varying signals and for effecting display of the trace on the display means; andd) wherein:i) the optical monitoring means produce time-varying signals including high frequency components of the detected light, wherein said high frequency components are above the fundamental systolic pulse and diastolic pulse frequencies;ii) the trace is derived from the time-varying signals, whereby the trace displays the high frequency components in the time-varying signals; andiii) the high frequency components are indicative of bioenergetic data.
