Measurement of pulmonary vessels by chest CT imaging has also been used to detect the presence of pulmonary hypertension. Despite the beneficial effects of oxygen therapy in patients with hypoxemia and COPD, LTOT does not lead to the normalization of pulmonary pressures Abraham et al or the reversal of morphologic derangements in the pulmonary vasculature Wilkinson et al N Engl J Med.
When it persists for more than three months each year for at least two years, in combination with sputum production and without another explanation, it is by definition chronic bronchitis.

An acute exacerbation a sudden worsening of symptoms  is commonly triggered by infection or environmental pollutants, or sometimes by other factors such as improper use of medications.
