Sonographic assessment of changes in diaphragmatic kinetics induced by inspiratory resistive loading

Background and objective Diaphragmatic breathing patterns under resistive loading remain poorly documented. To our knowledge, this is the first study assessing diaphragmatic motion under conditions of inspiratory resistive loading with the use of sonography. Methods We assessed diaphragmatic motion during inspiratory resistive loading in 40 healthy volunteers using M ‐mode sonography. In phase I of the study, sonography was performed during...
