The Inspired Sinewave Technique: A Comparison Study with Body Plethysmography in Healthy Volunteers
The inspired sinewave technique is a noninvasive method to measure airway dead space, functional residual capacity, pulmonary blood flow, and lung inhomogeneity simultaneously. The purpose of this study was to assess the repeatability and accuracy of the current device prototype in measuring functional residual capacity, and also participant comfort when using such the device. To assess within-session repeatability, six sinewave measurements were taken over 2-hour period in 17 healthy volunteers. To assess day-to-day repeatability, measurements were taken over 16 days in 3 volunteers.
