Shear-wave Elastography Compared to Respiratory Function Testing

Sponsor: Mayo Clinic

Summary

The purpose of this study is to evaluate the relationship between transdiaphragmatic pressure (Pdi) and diaphragm shear-wave elastography (SWE) during state-of-the-art respiratory muscle testing including volitional efforts (e.g., maximal inspiratory pressure, maximal expiratory pressure, Valsalva maneuver), as well as maximal phrenic nerve stimulation.

Official title: Comparison of Shear-wave Elastography to State-of-the-art Respiratory Function Testing to Measure the Range of Forces Generated by the Diaphragm Muscle
