A double-blind trial of nocturnal supplemental oxygen for sleep desaturation in patients with chronic obstructive pulmonary disease and a daytime PaO 2 above 60 mm Hg. The average rate of increase in pulmonary arterial pressure was 0. The pathophysiologic mechanisms of hypoxic pulmonary vasoconstriction are not fully understood but are believed due to direct and indirect effects of lowered oxygen levels on the pulmonary vascular smooth muscle cells Hida et al Pilates et al Definition, epidemiology, and risk factors”.

Both of these changes result in increased blood pressure in the pulmonary arterieswhich may cause cor pulmonale. RV systolic pressure is calculated as the sum of the trans-tricuspid gradient plus the estimated right atrial pressure RAP. The chance of quitting is improved with social support, engagement in a smoking cessation program, and the use of medications such as nicotine replacement therapybupropionor varenicline.

Further puljonale are needed to validate this finding and to assess the effect of chronic theophylline pulmona,e on COPD associated PH.

Because these vascular changes were similar to the alterations reported in PH associated with high altitude, Hicken et al hypothesized that PH associated with hypoxic lung diseases such as COPD was caused solely by hypoxic vasoconstriction and arteriolar muscular hyperplasia.

However, the degree of intimal thickening is proportional to the increase in pulmonary pressure during exercise and this relationship is thought to be due in part to decreased distensability and recruitment within the abnormal pulmonary vasculature Kubo et al Arterial oxygenation and pulmonary hemodynamics in patients with chronic airways obstruction.
