| description | A system for measuring a nasal valve collapse of a patient comprises: a facial mask (100) adapted to form a seal with a facial structure of the patient, the facial mask including an endoscope port (102) and an opening to allow air flow; an air flow sensor (108) in fluid communication with the opening of the facial mask configured to measure an air flow across the opening; an endoscope (120) with a camera adapted to pass through the endoscope port (102) in the facial mask and image a nasal valve; and a data acquisition module (112) configured to receive a plurality of images from the camera and a plurality of air flow measurements from the air flow sensor, determine (i) a first image of the plurality of images of the nasal valve taken during inhalation and (ii) a second image of the plurality of images of the nasal valve taken during a period between exhalation and inhalation, and determine, based on the first image and the second image, a size difference of the nasal valve during inhalation and during the period between exhalation and inhalation. |
