MATTEI, Romina Belén. Calculation of transpulmonary pressure through esophageal balloon monitoring during the full support phase of invasive mechanical ventilation. Argentinian j. respiratory physical therapy [online]. 2023, vol.5, n.3, pp.54-57.  Epub Nov 01, 2023. ISSN 2618-4095.  http://dx.doi.org/10.58172/ajrpt.v5i3.288.

Transpulmonary pressure (Ptp) is the difference between airway pressure and pleural pressure (Ppl). Measurement of esophageal pressure, as a surrogate for Ppl, allows for the calculation of Ptp and differentiation between respiratory mechanics and chest wall mechanics. For this purpose, there are two methods: the Talmor method and the Gattinoni method. Both provide useful information, particularly in subjects with acute respiratory distress syndrome, to individualize the lung protective ventilation strategy. The objective of this study is to describe the calculation of Ptp using both methods during the full support phase of invasive mechanical ventilation.

Keywords : respiratory mechanics; artificial respiration; esophageal manometry; acute respiratory distress syndrome.
