Figure 19 Maximum minute ventilation test interface
1) Real-time dynamic display of breathing volume-time curve.
2) Real-time dynamic display of tidal volume and respiratory rate during steady
breathing, guiding the user to measure the steady control progress value in the green
range.
3) Real-time dynamic pulmonary breathing state, intuitive reflection of the measurement
user in the inspiratory arrow down, expiratory arrow up, guide the patient's respiratory
nodule.
4) Real-time dynamic display vent stability, when the tidal breathing steady state
baseline to red, the user can enter to the next step deep enough air, and then
immediately with the maximum amplitude of the respiration, the maximum rate of
sustained rebreathing.
