Supports objective lung volume assessment; hypothesis-generating for modern validation and adoption.

This research aims to establish normal standards for lung volumes and maximum breathing capacity to aid in diagnosing respiratory issues.
Assessment of total lung capacity (T.L.C.) and maximum breathing capacity (M.B.C.)
Measurement of timed vital capacity (T.V.C.)
Evaluation of intrapulmonary gas mixing efficiency
Normal ranges for lung volumes and maximum breathing capacity were established for effective diagnosis.
Different disease states show disturbances in ventilatory and distributive efficiency.
No single test suffices for comprehensive respiratory assessment due to the complexities of lung function.

Needham et al. (1954) studied this question.
