Abstract
A respiratory monitoring apparatus comprises at least one motion sensor and a processing device. The at least one motion sensor senses an angular motion of a measured part capable of indicating a respiratory motion, and outputs an angular velocity vector of the measured part; the processing device, connected to the motion sensor, extracts a respiratory angular velocity from the angular velocity vector, and acquires a respiratory wave according to the respiratory angular velocity.
