RESPIRATORY INFORMATION DETECTION METHOD AND TUBE FOR RESPIRATORY INFORMATION DETECTION USED FOR THE SAME

PROBLEM TO BE SOLVED: To provide a respiratory information detection method capable of surely detecting the change of the air flow of respiration for both mouth respiration and nose respiration and preventing a body fluid from entering into a hole formed on a tube, and to provide the tube for respiratory information detection used for the respiratory information detection method.SOLUTION: In the respiratory information detection method, a detector and/or a pump is connected to one end of a medical tube having a first lumen provided with at least one hole on a part to be indwelled near the pharynx of a patient by inserting the other end through a nasal cavity or an oral cavity, and respiration information is detected on the basis of pressure variation near the pharynx part of the patient by the detector.
