  • In study 004, pirfenidone reduced decline in forced vital capacity ( FVC ) ( p = 0.001 ).
  • _Forced vital capacity showed how much air they could get out after taking a deep breath and blowing out as hard and as fast as they could.
  • COPD is defined as a forced expiratory volume in 1 second to forced vital capacity ratio ( FEV1 / FVC ) that is less than 0.7.
  • Further evaluation of a person's respiratory function can be done by assessing the minute ventilation, forced vital capacity ( FVC ), and forced expiratory volume ( FEV ).
  • :: I thought : static lung volumes don't change-so Total lung capacity, residual volume, functional residual capacity; dynamic lung volumes can change-so tidal volume, forced vital capacity, FEV 1.
  • The results confirmed observations from previous clinical studies that pirfenidone significantly reduced IPF disease progression as measured by change in percent predicted forced vital capacity ( FVC ) from Baseline to Week 52 ( rank ANCOVA p < 0.000001 ).
  • The primary efficacy endpoints of the study sought to determine the effect of Myozyme on functional endurance as measured by the six-minute walk test and to determine the effect of aglucosidase alfa on pulmonary function as measured by percent predicted forced vital capacity.
  • Average values for forced vital capacity ( FVC ), forced expiratory volume in 1 second ( FEV1 ) and forced expiratory flow 25 75 % ( FEF25 75 % ), according to a study in the United States 2007 of 3, 600 subjects aged 4 80 years.
  • On spirometry, as a restrictive lung disease, both the FEV1 ( forced expiratory volume in 1 second ) and FVC ( forced vital capacity ) are reduced so the FEV1 / FVC ratio is normal or even increased in contrast to obstructive lung disease where this ratio is reduced.
  • The most common parameters measured in spirometry are Vital capacity ( VC ), Forced vital capacity ( FVC ), Forced expiratory volume ( FEV ) at timed intervals of 0.5, 1.0 ( FEV1 ), 2.0, and 3.0 seconds, forced expiratory flow 25 75 % ( FEF 25 75 ) and maximal voluntary ventilation ( MVV ), also known as Maximum breathing capacity.
