WebIt is, therefore, generally more useful to use the Vd / Vt ratio: the alveolar ventilation will then be (1 − Vd / Vt) × the respiratory minute volume. Thus if the physiological dead space is 30% of the tidal volume (i.e. Vd / Vt = 0.3), then the alveolar ventilation will be 70% of the minute volume. Web14 jul. 2024 · Tidal volume is defined as the amount of air exchange in normal breathing. In other words, tidal volume is the differential between air inhaled and exhaled by a particular person. Typically, when calculating tidal volume and other respiratory scientific figures, researchers will use a respirometer, which the subject blows into.
