Vital capacity is the maximum amount of air that ... The average breathing rate is 12 breaths per minute. Tidal volume (TV) is the amount of air breathed in with each normal breath.

The volume inside the chest decreases. The pressure inside the chest increases and air is pushed out of the lungs through the mouth. You can increase your vital lung capacity by exercising regularly.

Spirometry was first invented in the 1840s by an English surgeon called John Hutchinson, who realised that lung volume or forced vital capacity was related to mortality. 185 years later, spirometry is ...

In general, the capacity of the pulmonary system far exceeds the demands ... recruited during progressive exercise to cause a reduction in end-expiratory lung volume. Flow rates increase, but airway ...

Participants with higher forced vital capacity, indicating better lung function, were less likely to develop heart disease, diabetes, and stroke over 10 years.

This study demonstrates the variations in the volume of expired gas resulting ... In an additional 30 patients with pulmonary emphysema the fast vital-capacity test was performed before the ...

Background—Pulmonary diffusing capacity for carbon monoxide (Dlco), alveolar capillary membrane diffusing capacity (Dm), and pulmonary capillary blood volume (Vc) are all significantly reduced after ...

To investigate the modulatory effect of sudium hydrosulfide on lung tissue-oxidized glutathione and total antioxidant capacity in the development of hypoxic pulmonary hypertension (HPH).
