9 Ιαν 2023 · The direct measurement of pleural pressures during thoracentesis is known as pleural manometry. The indications, technique, and interpretation of pleural pressures during pleural fluid manometry will be reviewed here.
Pleural pressure, or Ppl, is the pressure surrounding the lung, within the pleural space. During quiet breathing, the pleural pressure is negative; that is, it is below atmospheric pressure. The pleura is a thin membrane which invests the lungs and lines the walls of the thoracic cavity.
Pleural manometry (PM) is a novel tool that allows direct measurement of the pressure in the pleural space in the presence of either a pleural effusion or a pneumothorax. Originally it was used to guide therapy for tuberculosis (TB) before the development of anti-TB medications.
29 Ιουλ 2021 · A unique feature of the pleural cavity is the negative, sub-atmospheric, pressure within this space, ranging between −3 and −5 cmH 2 O at functional residual capacity (FRC) and −6 to −10 cmH 2 O during the inspiratory phase of quiet breathing [1•, 2].
3 Σεπ 2017 · Subatmospheric pleural pressure (Ppl), which is approximately −3 to −5 cmH 2 O at functional residual capacity (FRC) makes pleura a unique organ in the human body. The negative Ppl is critical for maintaining the lungs in a properly inflated state and for proper blood circulation within the thorax.

27 Σεπ 2019 · Pleural pressure is usually negative, due to the recoil of the chest wall, the recoil of the lungs, and the negative pressure exerted by the lymphatic system, The vertical pleural pressure gradient is the difference between the apical and basal pleural cavity pressures.
