— The Compass Thoracentesis makes Pleural Manometry Easy

Quickly diagnose trapped lung

Real time pressure monitoring enables the user to determine if there is a large (negative) change in pressure during pleural fluid removal.  Diagnosis of trapped lung helps facilitate further patient management.

Large volume thoracentesis

Recent evidence suggests that large volumes can be safely drained if pleural pressures are monitored, as long as the procedure is terminated if the patient develops anterior chest pain or the pleural pressure drops below -20 cm H2O(1,2).

Re-expansion pulmonary edema

Maintaining pleural pressure above -20 cm H2O can significantly reduce the risk of re-expansion pulmonary edema.  RPE, which currently develops in about 1% of thoracentesis procedures, is not only very expensive to treat but is also frequently lethal with a mortality rate close to 20%(2,3).

Treatment success

A measurement of lung elastance (by way of pressure) has been proven to be a predictor of successful pleurodesis(4).
