A patient interface and method of locating the patient interface for use particularly in spectroscopy applications. The patient interface includes a concave region and first and second convex regions. A wing extends from the concave region to help locate the patient interface properly. The convex regions provide additional adhesion support, particularly when used on the thenar eminence. The patient interface may be placed in a number of locations on a patient to determine an optimum location for measurement prior to affixing the interface to the patient.

Patient interface for spectroscopy applications

Embodiments of the invention provide a method and apparatus for using StOvalues to predict an outcome of a subject's health status.

[object Object]

A patient interface and a method of installing a patient interface for a spectroscopy kit on a patient. The patient interface includes a butterfly-shaped patient interface with a cap on top of the patient interface and in proximity to an optical head.

A disposable tip adapted for use in connection with an optical probe of an instrument. The tip includes a one-piece molded elastomeric base member having a boot and an opaque tissue-engaging surface. The boot releasably mates with and provides an interference/friction fit to the probe. The tissue-engaging surface surrounds and extends from the boot. A window in the base member extends into the boot to transmit light between the probe and tissue. A layer of optically transparent material covers the window on the tissue-engaging surface. Adhesive on the tissue-engaging surface of the base member releasably secures the probe to the tissue being analyzed.

A method of treating metabolic derangement is provided. Specifically, the method comprises the steps of administering an amount of an agent to alter cellular oxidative function while monitoring cellular oxidative function. The administration of the agent may be varied as a function of the monitored cellular oxidative function and will preferably be ceased when cellular oxidative function is restored.

Metabolic therapy directed at electron transport

A measurement system and method for measuring a relative concentration of a first form of a chromophore having a first form and a second form. The method comprises irradiating a tissue sample with light at a plurality of wavelengths within a wavelength range within which the first and second forms of the chromophore provide an overlapping spectral response. A detector is provided that detects spectral data emitted from the tissue. Furthermore, the method comprises determining a first and a second 2d derivative spectrum value, at first and second wavelengths, respectively, within said wavelength range at which the first 2d derivative spectrum value varies with the relative concentration of the first form of the chromophore. A scaled, 2d derivative spectrum value is derived from the first and second 2d derivative spectrum values. A memory stores a correlation which provides the relative chromophore concentration as a function of the scaled, 2d derivative spectrum value. Finally, the relative concentration of the first form of the chromophore in the tissue sample is determined from the 2d derivative spectrum values and the correlation.
