Michael Berthon Jones: Detection of apnea and obstruction of the airway in the respiratory system. ResMed, Holland & Hart, January 6, 1998: US05704345 (396 worldwide citation)

Methods and apparatus for determining the occurrence of an apnea, patency and/or partial obstruction of the airway are disclosed. Respiratory air flow from a patient is measured to give an air flow signal. The determination of an apnea is performed by calculating the variance of the air flow signal ...
