Raised-Volume Forced Expiratory Flow-Volume Curve in Healthy Taiwanese Infants

Abstract The raised-volume rapid thoracoabdominal compression (RVRTC) manoeuvre has been applied to obtain full forced expiratory flow-volume curves in infants. No reference data are available for Asian populations. This study was conducted to establish predictive reference equations for Taiwanese i...
