A multiscale model of vascular function in chronic thromboembolic pulmonary hypertension [PDF]
, 2021 Chronic thromboembolic pulmonary hypertension (CTEPH) is caused by recurrent or unresolved pulmonary thromboemboli, leading to perfusion defects and increased arterial wave reflections. CTEPH treatment aims to reduce pulmonary arterial pressure and reestablish adequate lung perfusion, yet patients with distal lesions are inoperable by standard surgical

The Interrelations of the Pulmonary Arterial and Venous Wedge Pressures [PDF]
Circulation Research, 1955 Pulmonary venous wedge pressure closely reflects the pulmonary arterial mean pressure. Pulmonary arterial wedge pressure is not significantly different from the left atrial mean pressure. Neither the former nor the latter is an approximation of the pulmonary capillary pressure.

Exercise Pulmonary Hypertension
Barcelona Respiratory Network Reviews, 2022 The clinical value of pulmonary hemodynamics during exercise has not been fully explored. In the last decade, several studies investigated the prognostic and diagnostic relevance of exercise hemodynamics and novel hemodynamic variables including the mean

Leading edge bluntness effects on the hypersonic flow over the double-wedge at multiple aft-wedge angles [PDF]
Physics of Fluids, 2023, 2023 The present numerical investigation focuses on the leading edge bluntness effects on the double-wedge with varied aft-wedge angles exposed to low enthalpy hypersonic free stream conditions. The bluntness ratio in this study varies, ranging from R/L1 = 0 (sharp leading edge) to R/L1 = 0.577 (maximum allowable bluntness), along with the aft-wedge angle ...
