Esophageal pressure measurements are used in to determine chest wall elastance and calculate
lung elastance and transpulmonary pressure in mechanically ventilated patients. A dedicated
esophageal balloon catheter is then placed in the esophagus to measure tidal variations in
In this study high resolution solid-state manometry technique was used to provide detailed
and continuous measurements of esophageal pressures in the different parts of the esophagus.
Measurements were performed during ongoing mechanical ventilation at different levels of
