The effects of pleural drainage on lung mechanics are unknown. Insertion of esophageal balloon will allow us to measure and assess pleural pressure, and thus assess any possible effects of pleural fluid drainage may have on lung mechanics.
Esophageal balloon will be inserted prior to pleural fluid drainage.

chest wall and lung compliance
The use of esophageal balloon allows us to partition respiratory system into its components, namely, chest wall and lung compliance. These measurements have not been described so far in patients undergoing pleural fluid drainage. Thus, assessment of esophageal pressure which is a surrogate of pleural pressure will allow us an accurate measurement of the effect of pleural fluid drainage on chest wall and lung mechanics.
Time frame: 1 year
oxygenation
We suspect that pleural fluid drainage will be associated with improved chest wall and lung mechanics. If this will be the case, then we expect a concomitant improvement in oxygenation.
