Abstract

Introduction: Pregnancy is associated with physiological changes in the control of respiration, in lung volumes, in the mechanics of breathing and in fluid electrolyte as well as in acid base balance. The different static lung volume changes during pregnancy rapidly goes to the normal after delivery along with descent of diaphragm and decompression of lungs. Our objective in this study was different lung volume changes in different trimester of pregnancy by spirometry.Materials &Methods: The study consists of recording of lung function tests of 4 groups of female subjects including pregnant women of various phages of pregnancy period i.e., 12 weeks (1st. trimester), 24weeks(2nd. Trimester), 36 weeks (3rd. trimester) and control group of non-pregnant women. The different static lung function parameters measured in this study were Expiratory Reserve Volume (ERV), Tidal Volume (TV), Vital Capacity (VC), Residual Volume (RV), and Minute Volume (MV).Results: We observed a statistically significant decrease in ERV and RV and a significant increase in TV,VC and MV in different trimesters in pregnancy.Conclusion: From the results of this study, it can be concluded that significant changes in lung function physiology occur during pregnancy which are necessary to meet the increased increase metabolic needs of the mother and fetus.
