Abstract

Background: Dynamic PFTs are an important tool in the evaluation of the functional as well as fitness state of the respiratory system, also for the assessment of severity of illness. Objective: To assess the effect of single normal pregnancy on expiratory flow rates. Patients and methods: A cross- sectional analytical study was conduct in the unit of pulmonary function in association with the Department of Gynecology and Obstetrics, in Baghdad teaching hospital in Baghdad. The study consists of recording the Pulmonary Function Tests for two major groups of Iraqi female of childbearing age. Including 120 pregnant women of various phases of gestational period subdivided into 10 weeks (I trimester), around 24 weeks (II trimester), 37 weeks (III trimester) and control group of 40 non pregnant women of age and sex compatible. All the participants were included in the study detailed history, and a complete clinical examination. The study includes two-group (pregnant and non-pregnant) aged from 16-44 years, of different weight; height (which recorded) and different conception from 1st, 2nd and 3rd trimesters were included. The nature and the purpose of the study also it explained to each participant. Results: There was statistically significant difference of mean age between the groups. There was no statistically significant difference in BMI between two groups at p. value less than 0.05. Conclusion: There is difference in PEFR between the pregnant and the non- pregnant but no difference among the different trimesters of the different pregnancy. Recommendation: we recommend monitoring the peak expiratory flow rate also as an important parameter for small airway disease monitoring.
