  • Gas sensor
    Patent number: 8449473
    Abstract: A method of determining the respiratory function of a subject is disclosed, the method comprising measuring the concentration of water vapor in the gas stream exhaled by the subject, and from the measured water vapor concentration determining the respiratory function of the subject. Mathematical techniques for analyzing the data obtained from the measurement of concentrations of gaseous components in an exhaled gas stream are also disclosed and their use in determining the lung function of a subject.
    Type: Grant
    Filed: April 10, 2008
    Date of Patent: May 28, 2013
    Assignee: Anaxsys Technology Limited
    Inventors: Mark Sinclair Varney, Michael Garrett, Deryk John Peter Williams
  • Detection of respiratory system lesions
    Patent number: 8403861
    Abstract: Humidity profiles of exhaled air of individuals obtained using a sensor to detect water vapor content or temperature versus time of exhalation may exhibit an irregularity indicative of a space-occupying respiratory system lesion. Detection of such irregularities provides an inexpensive and rapid means of pre-screening individuals for lung cancer diagnosis, and is applicable even to individuals with other respiratory disorders such as asthma and COPD.
