Solid-state esophageal pressure sensor for the estimation of pleural pressure: a bench and first-in-human validation study.

ABSTRACT:

Background

Advanced respiratory monitoring through the measurement of esophageal pressure (Pes) as a surrogate of pleural pressure helps guiding mechanical ventilation in ICU patients. Pes measurement with an esophageal balloon catheter, the current clinical reference standard, needs complex calibrations and a multitude of factors influence its reliability. Solid-state pressure sensors might be able to overcome these limitations.

Objectives

To evaluate the accuracy of a new solid-state Pes transducer (Pes_solid). We hypothesized that measurements are non-inferior to those obtained with a properly calibrated balloon catheter (Pes_bal).

Methods

Absolute and relative solid-state sensor Pes measurements were compared to a reference pressure in a 5-day
