COMPARISON OF BOTH STATIC AND DYNAMIC PULMONARY FUNCTION TEST PARAMETERS IN INDIAN PREGNANT AND NON-PREGNANT WOMEN
Abstract
Background- Pregnancy is characterized by sequence of dynamic physiological changes that impact on multiple organ system functions and is associated with various changes in pulmonary anatomy and physiology.
Methods-This was an observational study. A total of 30 pregnant women of 20–30 years of age in their third trimester of normal pregnancy (study group) and 30 nonpregnant women (control group) volunteered for the study.
Results- The difference in mean values of forced vital capacity (FVC), forced expiratory volume at the end of first second (FEV1 ), and FEV1 /FVC% in pregnant and non-pregnant women was not significant statistically (p > 0.05).
Conclusion-Pregnancy has important effects on pulmonary functional parameters in each trimester. But the susceptibility to such alterations are variable.
