Document Type and Number:
WIPO Patent Application WO/2023/125451
Kind Code:
A1
Abstract:
Embodiments of the present application relate to the technical field of medical instruments and provide a breathing phase determination method and an apparatus, which aim to solve the technical problems where breathing phase determination requires an additional apparatus, and where same is structurally complex. The method comprises: acquiring a gas flow value in a breathing pipeline, and acquiring a pressure value of a pressure sensor, the pressure sensor being used for capturing the pressure in the breathing pipeline; converting the gas flow value and the pressure value into a first value and a second value under a same standard; and determining the current breathing phase of a patient according to the difference between the first value and the second value. As a consequence, the breathing phase of the patient can be determined by means of the gas flow value and the pressure value of the breathing pipeline.
