Hypoxic pulmonary vasoconstriction is considered as one of the factors leading to pulmonary hypertension in patients with chronic bronchitis, but the magnitude and the variability of the pulmonary vascular response to hypoxia in these patients have not been well established. We investigated the pulmonary hemodynamic changes induced by breathing two hypoxic mixtures (FIO2 = 0.15 and 0.13) in 26 ...
