The maximum breathing capacity test.
Since the introduction of this test by Hermannsen (1933), the measurement of maximum breathing capacity (M.B.C.) on different groups of subjects has been reported on several occasions (for example, Gray and Green, 1945; Baldwin, Cournand, and Richards, 1948; Wright, Yee, Filley, and Stranahan, 1949; and Gilson and Hugh-Jones, 1949). Most investigators have performed this test with a spirometer,...
متن کاملThe relation between the fast vital capacity curves and the maximum breathing capacity.
The maximum breathing capacity (M.B.C.) of an individual is defined as the greatest amount of air he can breathe in one minute. The test in which it is measured was introduced by Hermannsen (1933) as a test of the mechanical efficiency of the respiratory apparatus. Since then it has been widely accepted as fulfilling that purpose and has been quoted (Gray, Barnum, Matheson, and Spies, 1950) as ...
متن کاملThe effect of the rate of breathing on the maximum breathing capacity determined with a new spirometer.
Very few quantitative observations have been reported on the effect of rate of breathing on the voluntary maximum breathing capacity (M.B.C.). Proctor and Hardy (1949) found that the M.B.C. was achieved at a rate of 30 respirations per minute (R.P.M.). At higher rates of breathing the ventilatory capacity was diminished. These observations are contrary to the findings of other investigators who...
متن کاملMaximum flow ratios at mid-vital capacity in young healthy adults.
Upper airway obstruction is usually diagnosed by visual examination of maximum expiratory and inspiratory flow-volume curves and by calculating a ratio of expiratory to inspiratory flow at 50 percent of vital capacity (mid-vital capacity flow ratio); however, reference values of this ratio have not been well established, and considerable variability exists. The purpose of this study was to exam...
متن کاملIn health--vital capacity is maximum in supine position.
Vital capacity, frequently measured clinically as an index of pulmonary function, gives useful information about the strength of respiratory muscles and other aspects of lung functions. It is generally noted in sitting position. As in the supine position, respiratory excursions of diaphragm is highest in normal breathing, this study was planned to note whether there occurred any alteration in v...
