Abstract Background Acute alveolar hypoxia causes pulmonary vasoconstriction HPV which serves to match lung perfusion to ventilation. The underlying mechanisms are not fully resolved yet. The major vascular segment contributing to HPV the intra-acinar artery is mostly located in that part of the lung that cannot be selectively reached by the presently available techniques . hemodynamic studies of isolated perfused lungs recordings from dissected proximal arterial segments or analysis of subpleural vessels. The aim of the present study was to establish a model which allows the investigation of HPV and its underlying mechanisms in small intra-acinar arteries. Methods Intra-acinar arteries of the .
