Abstract

A method and a device for calculating a minute ventilation of a medical breathing apparatus. The method comprises: recording breathing data in real time, the data comprising time of each inspiration and an expiratory tidal volume of breathing prior to each inspiration (S102); and each time when breathing data is recorded, calculating a minute ventilation of the medical breathing apparatus according to the data recorded in the current recording operation and in a preset time duration before the current recording operation (S104). The method can calculate the minute ventilation of a patient quickly and accurately, thereby solving the problem of slow measurement of ventilation in unit time in the prior art.

Description

technical field [0001] The invention relates to a calculation method and device for minute ventilation of medical breathing equipment. Background technique [0002] For some respiratory devices currently on the market, the minute ventilation is accumulated according to the tidal volume of all breaths in one minute. Although this calculation method is accurate, but the response is slow, it takes a minute to react. For frequent changes in respiratory rate, this calculation method may not capture the inverse ventilation changes. [0003] In the prior art, there is a problem of slow response to the determination of the ventilation volume per unit time, for which no effective solution has been proposed so far. Contents of the invention [0004] The main purpose of the present invention is to provide a method and device for calculating the minute ventilation of medical respiratory equipment, so as to solve the problem of slow response in determining ventilation per unit time i...
