Pleural Manometry Summary

Measurement of Intrapleural Pressures and Pleural Elastance during therapeutic thoracentesis can be used to identify pleural pathologies such as trapped lung and entrapped lung and to predict successful pleurodesis. It may also reduce the risk of re-expansion pulmonary edema.

pleural pressure measurement:

1) Connect a manometer (water column, pressure transducer, or digital manometer) behind a 3-way stopcock.

2) Withdraw fluid using using a syringe and collecting bag as you would normally 

3) Measure the intrapleural pressure at end-expiration intermittently (e.g. every as fluid is removed by thoracentesis and calculate pleural elastance
