Esophageal balloon calibration during Sigh: A physiologic, randomized, cross-over study
Journal of Critical Care(2021)
Abstract
•Esophageal pressure is usually employed as surrogate of pleural pressure.•Esophageal balloon calibration may be used to obtain more accurate esophageal and transpulmonary pressure assessment.•Optimal filling volume is affected by intrathoracic pressure.•Sigh breath requires a higher optimal filling volume compared to tidal breath.
