The total lung capacity ( TLC ), functional residual capacity ( FRC ), residual volume ( RV ), and vital capacity ( VC ) are all values that can be tested using this method.
22.
If the vital capacity has dropped below 40 % of normal, a volume ventilator / respirator may be used during sleeping hours, a time when the person is most likely to be underventilating ( hypoventilating ).
23.
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 ).
24.
The symptoms appear in the upper chest region ( Pulmonary function measurements are reduced, as noted by a reduction in the amount of air that the lungs can hold ( vital capacity ) and changes in expiratory function and lung elasticity.
25.
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.
26.
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.
27.
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.
28.
Here is a report that remarks on this : " " Paralysis of the diaphragm may be suspected in a patient . . . in whom the vital capacity falls appreciably in the supine position " . " [ Talk ] 10 : 44, 23 December 2010 ( UTC)
29.
Both inspiratory and, indirectly, expiratory muscle function can be assisted by GPB . GPB can provide an individual with weak inspiratory muscles and no vital capacity ( VC ) or breathing ventilator-free breathing tolerance with normal alveolar ventilation and perfect safety when not using a ventilator or in the event of sudden ventilator failure day or night.
30.
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.
