WebbMinute ventilation (VE) is the total volume of gas entering (or leaving) the lung per minute. It is equal to the tidal volume (TV) multiplied by the respiratory rate (f). Minute ventilation = VE = TV x f At rest, a normal person moves ~450 ml/breath x 10 breath/min = 4500 ml/min. Webb5 juli 2024 · This volume is considered to be 30% of normal tidal volume (500 mL); therefore, the value of anatomic dead space is 150 mL. Physiologic or total dead space is equal to anatomic plus alveolar dead space which is the volume of air in the respiratory zone that does not take part in gas exchange. saddle shoes fashion
