Title:
RESPIRATORY RATE MONITORING METHOD AND MEDICAL VENTILATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/077448
Kind Code:
A1
Abstract:
A respiratory rate monitoring method (100) and a medical ventilation device. The method (100) comprises: acquiring a first signal and a second signal collected during the process of a medical ventilation device providing mechanical ventilation for a ventilation subject, wherein the first signal and the second signal can reflect the respiratory rhythm of the ventilation subject (S110); extracting a frequency domain feature of the first signal and, according to the frequency domain feature of the first signal, obtaining a first respiration rate of the ventilation subject (S120); extracting a time domain feature of the second signal and, according to the time domain feature of the second signal, obtaining a second respiration rate of the ventilation subject (S130); and according to the first respiration rate and the second respiration rate, obtaining a third respiration rate of the ventilation subject (S140). The described respiratory rate monitoring method (100) can increase the accuracy of respiratory rate monitoring.
