Mechanisms underlying pulmonary hypertension are not completely clarified. However, it has been shown that pulmonary blood flow, alveolar pressure or left atrial pressure and blood viscosity do not change at all during hypoxia. Furthermore, it has been reported that alveolar hypoxia produces an increase in pulmonary pressure by a vasoconstrictive response although the mechanisms responsible for this phenomenon remain unclear (1–4).
