New lung functions and pregnancy

Abstract

Newer lung function tests (e.g., flow volume-loops and closing volume), as well as standard pulmonary function tests, were performed on 19 healthy individuals in the third trimester and after delivery. We found that the flow characteristics, manifested in the FVL, and the CV remained unaltered during pregnancy. In regard to the standard pulmonary function tests, we found no statistically significant change except for a decrease in the ERV and in the FRC during pregnancy.
