Pleural Manometry Allows the Diagnosis of Unexpandable Lung
This statement is arguably the least controversial regarding manometry. The concept seems straightforward: At the resting condition (ie, at functional residual capacity), the pleural pressure is slightly subatmospheric, a function of the lung elastic recoil and the tendency of the chest wall to expand outward. Disruptions in capillary homeostasis, as described by Starling, result in an accumulation of pleural fluid and an increase in pleural pressure.3 Conversely, thoracentesis should lead to a
Pleural Manometry Helps Prevent REPE
Experts suggest that fluid removal should not exceed 1 L to avoid REPE, unless pleural pressure is monitored, in which case fluid can be removed until end-expiratory pleural pressures drop below −20 cm H2O or chest discomfort develops. The pathophysiology of REPE is still to be elucidated. However, animal models suggest that the development of REPE correlates with the duration of lung collapse and excessively negative pleural pressures,10, 11 which would suggest that the REPE may also be
Pleural Manometry Predicts Success of Pleurodesis
It is self-evident that for pleurodesis to be successful, there should be adequate apposition of parietal and visceral pleura after lung reexpansion. It should also make sense intuitively that high pleural elastance may interfere with pleurodesis because higher elastance represents a higher likelihood of the two pleural layers being pulled apart. This was elegantly demonstrated by Lan et al,12 who showed that a decrease in pleural pressure in excess of 19 cm H2O after removal of the initial 500
Conclusions
Lessons learned from the ongoing controversy surrounding the use of Swan-Ganz catheters in critically ill patients remind us that diagnostic tools can help only if the information provided is accurate and correctly interpreted and leads to appropriate interventions resulting in improved patient outcomes. Pleural manometry takes time, requires additional training, and may lead to inappropriate decisions. Given the present state of knowledge, it would be difficult to justify withholding chemical

Pleural manometry in patients with pleural diseases – the usefulness in clinical practice
2018, Respiratory MedicineCitation Excerpt :It might be argued that the absolute pleural pressure after pleural fluid removal may be a more relevant variable to consider, this issue certainly requires further studies. Pleural pressure measurement during thoracentesis is time consuming and requires adequate training [48–50]. Summarizing the above pros and cons for the use of pleural pressure measurement during thoracentesis, it should be agreed that pleural manometry may increase the safety of the procedure, provide useful clinical information that may significantly impact further management, is safe, easy to perform and does not add significant costs to the procedure [35].
