An oximetry device sealed in a sheath directs a user to allow the oximetry device to make oximetry readings at a number of different tissue locations of a patient and average two or more of the oximetry readings by directing the lifts and placements of the oximetry device and sheath to and from the different tissue locations and detecting the lift and placements. The averages are generated and displayed on a display of the device for the oximetry readings if the lifts are made while use directions for the lifts are displayed on a display of the oximetry device. The averages are not generated if the lifts are not made while the user directions for the lifts are not displayed. The averages are simultaneously displayed with the oximetry readings which are instantaneous measurement for patient tissue.

An automated assembly sensor cable has a generally wide and flat elongated body and a registration feature generally traversing the length of the body so as to identify the relative locations of conductors within the body. This cable configuration facilitates the automated attachment of the cable to an optical sensor circuit and corresponding connector. In various embodiments, the automated assembly sensor cable has a conductor set of insulated wires, a conductive inner jacket generally surrounding the conductor set, an outer jacket generally surrounding the inner jacket and a registration feature disposed along the surface of the outer jacket and a conductive drain line is embedded within the inner jacket. A strength member may be embedded within the inner jacket.

According to one aspect of the invention, there is provided a method for assessing blood flow regulation performance based on hemodynamics, comprising the steps of: calculating second biometric information corresponding to a time differential of first biometric information on a hemoglobin concentration measured from a cerebral part of a subject; and assessing blood flow regulation performance of the subject with reference to a response that occurs in the second biometric information in correspondence to a change in a posture of the subject.

A wearable sweat sensor for detecting one or more analytes in human sweat comprises an optical module comprising at least one light source and at least one light detector; at least one sensor layer optically coupled to the optical module and having optical absorbance properties that are dependent on the concentration of a target analyte of said one or more analytes; and one or more processors in communication with the optical module. The one or more processors are configured to: cause light from the at least one light source to be transmitted towards, and/or through, the at least one sensor layer; obtain, from the at least one light detector, one or more optical signals reflected and/or transmitted from the at least one sensor layer; and determine, from at least one wavelength component of the one or more optical signals, a target analyte concentration.

A fundus imager includes a camera for capturing eye fundus images, and a display for displaying the eye fundus images. The fundus imager captures an eye fundus video using the camera, performs an analysis on the eye fundus video to generate a signal, and calculates one or more vital signs from the signal.

Embodiments herein relate to devices and methods for assessing pulmonary status using optical oxygenation sensing. In an embodiment, an oxygenation monitoring device can be included having a first optical emitter, wherein the first optical emitter can be configured to emit light at a first wavelength from 100 nanometers (nm) to 2000 nm. The oxygenation monitoring device and further include a first optical detector, wherein the first optical detector can be configured to detect incident light. The device can be configured so that emitted light from the first optical emitter propagates through a lung tissue and detected incident light can be used to determine an oxygenation status of the lung tissue. Other embodiments are also included herein.
