The role of pulmonary function tests in pulmonary hypertension is to identify airway or parenchymal lung disease. In pulmonary arterial hypertension (PAH) there may be mild to moderate reduction in lung volumes and occasionally mild airflow obstruction, particularly at the peripheral level. Most people with PAH have decreased transfer factor.
