A sigmoid model of the static volume-pressure curve of human lung. 1975

M Paiva, and J C Yernault, and P V Eerdeweghe, and M Englert

The authors present a sigmoid mathematical model of the pressure-volume curve of the human lung, based on a relationship between the specific compliance and the maximal pulmonary volume: (see article). This model fits better the experimental data obtained in 20 young normal adults than the currently used exponential model of Salazar and Knowles (1964). The independence between the constant K' and body height is interpreted as a constancy of pulmonary structure for normal subjects of the same age range.

UI	MeSH Term	Description	Entries
D008170	Lung Compliance	The capability of the LUNGS to distend under pressure as measured by pulmonary volume change per unit pressure change. While not a complete description of the pressure-volume properties of the lung, it is nevertheless useful in practice as a measure of the comparative stiffness of the lung.
