摘要：
A respiratory monitoring system includes: a first sensing tube provided in a respiratory flow tube and provided with at least a first directional hole opened in a respiratory flow direction； a second sensing tube provided with at least a second directional hole corresponding to the first directional hole； a first sensing element configured to detect a first dynamic pressure (PL) using a differential pressure between gas flows from the first and second sensing tubes； a second sensing element configured to detect a second dynamic pressure (PH) using a differential pressure between gas flows from the first and second sensing tubes； and a computation unit configured to compute patient's respiration information including a tidal inspiratory volume and a tidal expiratory volume using the first and second dynamic pressures.
