![]() c) there will be no effect on either the partial pressure or diffusion rate of gases. 100 (2 ratings) Changes in ventilation rate affect the alveolar and pulmonary venous PO2 by the following way:- Under normal physiologic conditions, an increase in PCO2 causes a decrease in pH,which will increase minute ventilation and therefore increase alveolar ve. b) the partial pressure of carbon dioxide in the alveoli will increase. Under these conditions a) the partial pressure of oxygen in the alveoli will increase. Physiological dead space can occur due to changes in function, such as in cases of infection of the lung it will typically affect ventilation if the infection is in the lung and. posture positions: sitting, standing, lying) it will affect both ventilation (V) and perfusion (Q). Assume that whole-body metabolic rate (VO2) stays constant, but the alveolar ventilation rate (VA) is decreased. Anatomical dead space can occur due to changes in gravity (i.e. Functional Residual Capacity ( FRC)- It is the volume of gas in lungs after end expiration. Question: 1) Your subject has a tidal volume of 0.69 L/breath and a respiratory rate of 16 breaths/min and a dead space of 0.15L, what is their pulmonary ventilation (minute ventilation, VE) (no units required, round to 1 decimal place) 2) Your patient has an inspiratory capacity of 2. The product of tidal volume and the breathing frequency is equivalent to the a) pulmonary ventilation rate (VE) b) alveolar ventilation rate (VA) c) oxygen consumption rate (VO2) d) dead space ventilation 2. Total Lung volume- IRV+TV+ERV+RV 5500 to 6000ml.
