NCT02463773

Brief Summary

This is a proof of concept study where the investigators aim to study the correlation between the use of a simple bedside ultrasound measurement of diaphragmatic muscle excursion with established (but time consuming) measurements made to optimize an important setting on the mechanical ventilator (positive end expiratory pressure or PEEP) in intubated adults with acute respiratory distress syndrome (ARDS) in the medical ICU.

Outcome Measures

Primary Outcomes (1)

  • Feasibility

    This is a proof of concept study that investigates the degree of dorsal and ventral diaphragmatic excursion with bedside ultrasound during PEEP titration. Optimal PEEP management was guided by an esophageal probe calculating transthoracic pulmonary pressure. Each patient underwent a series of PEEP titrations for which data was recorded on diaphragm excursion (mm) and esophageal pressure (cmH2O). Diaphragm excursion (mm) was measured at the ventral and dorsal side using anatomic m-mode with bedside ultrasound. Esophageal pressure was measured using an esophageal probe which was placed at the bedside.
