WebMeasuring Lung Capacity with Spirometry Spirometry is a simple, noninvasive breathing assessment that can be used to determine overall lung health. During a spirometry assessment, an individual will inhale and exhale through a device called a spirometer. The spirometer will measure the volume of air that is passed through a sensor.

Are ethnic differences in lung function explained by chest size?

Web22 apr. 2024 · Summary. Ventilation is unevenly distributed across the lung because of the range of intrapleural pressures that are established down the lung by gravity. At normal lung volumes the base of the lung is better ventilated than the apex. At low lung volumes this relationship is reversed as intrapleural pressures at the base of the lung become ... WebFVC in whites was 13.4% bigger than in Asians of the same height, and the FEV 1 was 10.6% greater in whites. The influence of chest dimensions on lung function was trivial.
