Increase the alveolar volume

WebWhat happens to alveolar volume and intra-alveolar pressure during exhalation? 1. Decrease alveolar volume causes an increase alveolar pressure. 2. Increase alveolar volume causes an increase alveolar pressure. 3. Decrease alveolar volume causes a decrease alveolar pressure. 4. Increase alveolar volume causes an increase alveolar pressure WebMinute 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.
