Intrapulmonary distribution of blood flow during exercise in pulmonary hypertension assessed by a new combination technique

Intrapulmonary distribution of blood flow during exercise in pulmonary hypertension assessed by a new combination technique

BackgroundHyperventilation and inadequate cardiac output (CO) increase are the main causes of exercise limitation in pulmonary hypertension (PH). Intrapulmonary blood flow partitioning between ventilated and unventilated lung zones is unknown. Thoracic impedance cardiography and inert gas rebreathin...
