In addition, increased PVR can also be a consequence of hypoxic pulmonary vasoconstriction (HPV) under generalized hypoxia. Increased proliferation and migration of PASMCs are often associated with ...

But ever since 1946, when von Euler and Liljestrand 2 reported that acute hypoxia increased pulmonary arterial pressure attributable to pulmonary vasoconstriction, investigators have been hard at work ...

Germany The pulmonary circulation responds to hypoxia with vasoconstriction, a mechanism that helps to adapt to short-lived hypoxic episodes. When sustained, hypoxic pulmonary vasoconstriction (HPV) ...

Normally, when a patient has pneumonia, the tiny blood vessels around the fluid-filled areas of the lungs constrict (called hypoxic vasoconstriction): Sensing a lack of oxygen in the damaged areas ...

However, continuous HPV‐related vasoconstriction can induce shear stress–related vascular remodeling ... may be attributable to the magnitude of functional HPV in accordance with the degree of the ...

Hypoxia hypercapnia-induced pulmonary arterial hypertension (HHPH) is a chronic and progressive disease with poor diagnosis and leads to right heart failure and eventually death due to lack of proper ...

In chronic obstructive pulmonary disease, long-term oxygen therapy ameliorates pulmonary hypertension and greatly improves survival, although the correction of alveolar hypoxia and pulmonary ...

Pulmonary hypertension is a well recognised complication of chronic hypoxic lung diseases, which are among the most common causes of death and disability worldwide. Development of pulmonary ...

Hypoxic pulmonary vasoconstriction (HPV) is a physiological mechanism that protects against systemic hypoxemia by redistributing blood flow from poorly to better ventilated areas of the lung, thereby ...
