How do Diuretics help pleural effusion?
Purpose: Diuretic therapy increases the total protein and lactate dehydrogenase concentrations in pleural fluid in patients with transudates due to heart failure, but the effect of diuresis on other substances in pleural fluid constituents is not known.
Can diuretics drain pleural effusion?
Diuretics and other heart failure medications are used to treat pleural effusion caused by congestive heart failure or other medical causes. A malignant effusion may also require treatment with chemotherapy, radiation therapy or a medication infusion within the chest.
How does CHF cause pleural effusion?

What do you need to know about pleural fluid?
Interpreting pleural fluid results correctly requires an awareness of the possible aetiologies of a pleural effusion and an understanding of the reliability of the outcome of each investigation.
How are laboratory tests used to diagnose pleural effusion?
Laboratory testing helps to distinguish pleural fluid transudate from an exudate. The diagnostic evaluation of pleural effusion includes chemical and microbiological studies, as well as cytological analysis, which can provide further information about the etiology of the disease process. Immunohistochemistry provides increased diagnostic accuracy.
Why do diuretics decrease potassium in the blood?
Yes, some diuretics — also called water pills — decrease potassium in the blood. Diuretics are commonly used to treat high blood pressure (hypertension) because they lower blood pressure by helping your body eliminate sodium and water through your urine. However, some diuretics can also cause you to eliminate more potassium in your urine.
