Diaphragm Ultrasound Measurements With Variations in Modes of Ventilation

NCT04319939 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 66

Last updated 2025-12-26

No results posted yet for this study

Summary

The overall objective of the study is to conduct an observational study involving intensive care unit patients receiving mechanical ventilation and determine if there are differences in diaphragm thickness ultrasound measurements during expiratory and inspiratory phases in a controlled and spontaneous mode. For patients receiving sedatives, an additional set of measurements will be taken during a standard of care interruption of sedatives

Conditions

  • Mechanical Ventilation

Interventions

OTHER

Assist Control Mode and Pressure Support Mode Mechanical Ventilation

Diaphragm ultrasound measurements (end expiration and peak inspiration thickness) will be performed in assist control mode and pressure support mode mechanical ventilation in each participant. The participant will thus serve as his/her own control for these interventions.
