The Effect of Posture on Diaphragmatic Movement and Vital Capacity in Normal Subjects

“…We have found only one previous description of the lifting of the diaphragm due to movement of the thoracic cage in deep inspiration (Jamin, 1906). Fig.…”

“…The upper lobes of the lungs were expanded by movement of the upper ribs and operculum of the thoracic cage, and the lower lobes and the posterior parts of the lung, which lay in the paravertebral grooves, were expanded mainly by diaphragmatic movements. Jamin (1906) observed changes of the level of the diaphragm with changes of posture. He gave no measurements of diaphragmatic excursion, but he described upward movement of the diaphragm during inspiration in normal subjects due to lifting and expansion of the thoracic cage.…”
