  • Methods for measuring lung function using diffused light
    Patent number: 5606969
    Abstract: The method and device of the invention provides a measure of lung function at a preselected region of the lung by detecting and measuring light scattering following contact of the light onto lung tissue. Multiple parameters concerning the status of the lungs can be measured using a variety of wavelengths of light targeted at the lung tissue. In this way it is possible to determine regions of impaired lung function in patients with emphysema. The device utilizes an optical fiber, a light collection system and a spectral separation device to provide an image of the lung and to determine functional parameters such as gas exchange.
