<p>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.</p> |
