Summary Arterial blood gases, physiological dead space and percentage pulmonary venous admixture (physiological shunt) were measured in 31 patients with proteinuric pre‐eclampsia. There was no difference in pulmonary function in 22 patients with moderate pre‐eclampsia when compared with normal pregnancy, but in 9 patients with severe pre‐eclampsia, there was a significant increase in alveolar‐to‐arterial P o 2 difference and physiological shunt, indicating a degree of pulmonary ventilation/perfusion imbalance. There was no accompanying hypoxaemia, suggesting that the impairment was of no clinical importance.
