  • Decline in Lung Volume With Duchenne Muscular Dystrophy

    In this situation, the volume that oxygen and carbon dioxide has to pass by diffusion for gas exchange increases. We used 4% sulfur hexafluoride for the MBW studies, which has a higher molar mass compared with air. This heavy gas might deposit in the large residual volume and barely be cleared by the low FVC and low V T in patients with DMD. Unfortunately, we were not able to do a phase III slope

  • Novel methodology to perform sulfur hexafluoride (SF6

    The Exhalyzer D has been used previously to perform sulfur hexafluoride (SF 6) MBW, but based on the mainstream molar mass (MM) signal to calculate FRC and lung clearance index (LCI), and not on the true SF 6 concentration (11, 17). Using the mainstream MM signal is advantageous in that it does not require synchronization with respiratory flow.
