Lung function and postural changes during pregnancy

Respir Med. 1989 Nov;83(6):467-70. doi: 10.1016/s0954-6111(89)80127-1.


The aim of this study was to determine the effects of postural changes on lung function in pregnant women during the first, second, third trimester and post partum. A significant decrease in FRC, PEF and FEV1 was observed as a result of the postural changes. Arterial oxygenation, MVV and DLCO remained largely the same.
