Effect of advanced normal pregnancy on pulmonary function tests
DR. PATIL HEMLATA J, DR. DEOKAR NA
Background: The physiological adaptations of the pregnant woman
involve the circulatory, respiratory, digestive, renal, endocrine and
metabolic systems. Their precise knowledge allows the clinician to verify
the extent of the adaptation in pregnant women and helps to avoid
unnecessary treatment of physiological changes misinterpreted as
pathological changes in reference to pre-pregnancy standards. We
designed the study to understand changes in pulmonary function tests
during advanced pregnancy.
Results: In all subjects of the study group there was decrease in Forced
Vital Capacity (FVC) and Forced Expiratory Volume (FEV1) but FVC
decreases more than FEV1 so the FEV1/FVC ratio is seen to be increased
as compared to the control group. The results were found to be
statistically significant (p<0.05).
Conclusion: It is concluded that pulmonary function tests like FVC and
FEV1 decreases due to gravid state in advanced pregnancy.
