Determination of %FVC (FEV/FVC%) at expiratory flow rate of 1 lit/sec and 0.5 lit/sec from forced expiratory spirogram.
A method for determination of %FVC (FEV/FVC%) at forced expiratory flow rate (FEF) of 1 lit./sec. and 0.5 lit/sec from the forced expiratory spirogram is described. This parameter is simpler to determine and is a better expression of end expiratory flow rate than FEF 75%-85%.
