Question

What is the level of ph in plueral effusion if it is due to other than lung pathology?

Answer 1

Explanation:

These are esophageal rupture, tuberculosis, rheumatoid disease, pneumonia and malignant disease. Of these, esophageal rupture is associated with the lowest pleural fluid pH, usually in the range of 5.0-6.5. A review of 475 patients with pleural effusion [14] revealed 59 patients with pleural fluid pH <6.0.
