WebVital capacity(VC), the volume of exhaled air after maximal inspiration, normally is 60 to 70 mL/kg and in normal persons is determined primarily by the size of the thorax and lungs. … WebBackground: The assumption that the assessment of forced expiratory flow between 25% and 75% of vital capacity (FEF (25-75)) does not provide additional information in asthmatic children with normal FEV (1) percent predicted has not been adequately tested.
WebNo significant differences were found with regard to either the ratio between forced expiratory volume in 1 s and forced vital capacity or forced expiratory volume in 1 s. The majority of firefighters had diffusing capacity of the lung for carbon monoxide, oscillometry and single-breath nitrogen washout values within the normal ranges. WebMaximal voluntary ventilation (MVV), also referred to as maximal breathing capacity (MBC), is defined as the maximum minute volume of ventilation that the subject can maintain for 12 to 15 s. In the normal subject MVV is about 15 to 20 times the resting minute volume. The subject simply breathes in and out of a spirometer without the need …

WebThe reserve volume is the amount of air that remains in the lungs and passageways after a maximal expiration. Vital capacity is the total of the tidal volume, inspiratory reserve volume, and expiratory reserve volume.
