Abstract
Introduction: Pregnancy isassociated with physiological changes in control of breathing and lung volumes.
Aim: The aim of the present study was to describe the pulmonary function tests changes in pregnant and non-pregnant individuals.
Materials and Methods: The study consists of recording pulmonary function tests of four groups of female subjects including pregnant women of various phases of gestational periods that is 12wks(1st trimester), 24wks (2nd trimester), 36wks (3rd trimester) and control group of non-pregnant women. The study was conducted in pregnant and non-pregnant subjects (n=100) aged between 20-35 years, first the respiratory function values were taken in control group and the parameters selected for the study were expiratory reserve volume, tidal volume, vital capacity, residual volume, minute volume, case group involves75 pregnant individuals of all the three trimesters were randomly selected from the population.
Result: The results showed statistically significant reduction in expiratory reserve volume and residual volume, there was significant increase in tidal volume, vital capacity and minute volume in three different trimesters of pregnancy.
Conclusion: The data revealed that both from the study and the materials collected concerning respiratory physiology and pregnancy suggest that pulmonary function tests changes during healthy pregnancies should be interpreted cautiously in pregnant women with impaired lung functions.
Keywords: Expiratory Reserve Volume (ERV), Residual Volume(RV), Vital Capacity(VC), Minute Volume (MV)
