  • Title: [Measurements of P-V curves of the lungs and its use in clinical assessment].
    Author: Lin JT.
    Journal: Zhonghua Jie He He Hu Xi Za Zhi; 1991 Jun; 14(3):159-61, 191. PubMed ID: 1913964.
    Abstract:
    Pressure-volume curves of the lungs in 112 healthy nonsmokers and 39 patients with obstructive emphysema or pulmonary interstitial diseases were studied. Normal values by decade/sex groups and regression formulas for dynamic compliance at 20 breath/min (CLdyn20), statis lung compliance (CLst) and maximal static lung recoil pressure (Pst(L)max) against age, height, weight, and body surface area were calculated. Various factors affecting the lung compliance we studied. Our studies confirmed the high CLst, loss of Pst(L)max in patients with obstructive pulmonary emphysema, and also showed that there are reduction of CLst and increase of Pst(L)max in patients with pulmonary interstitial diseases.
