Comparison of air-displacement plethysmography results using predicted and measured lung volumes over a protracted period of time.

abstract：:This study takes a novel approach to describing time-related changes in dynamic cerebral autoregulation (dCA). It is well-recognized that dCA exhibits both intra- and inter- subject variability, and this study seeks to characterize the extent to which intra-subject variability occurs after a significant period of time...
