Document Type and Number:
Japanese Patent JP4235455
Kind Code:
B2
Abstract:
A method for measuring nitric oxide concentration in exhaled air through a blow tube of a measuring equipment. The nitric oxide concentration is measured in the exhaled air flowing in the blow tube, a flow rate of the exhaled air flowing through the blow tube is measured during the exhalation and flow resistance of the blow tube is adjusted on the basis of the measured flow rate value such that the flow rate of the exhaled air substantially remains at a preset value. The method is used to diagnose an inflammatory lung disease in a patient whereby an increased nitric oxide concentration indicates an inflammatory lung disease, such as alveolitis.
