The human respiratory system consists of a series of structures and organs that inhales oxygen from the environment, holds it inside the body and expels carbon dioxide as waste product. Many techniques and instruments are available for evaluating respiration, the aim of this research is to: i) study the Pulmonary Function Test (PFT) during different trimesters of pregnancy and do tests for ordinary non-pregnant women, which are performed by using Spirometer and PowerLab instruments and appropriate software; ii) study the influences of pregnancy on expiration of women, and iii) using Statistical Package for Social Sciences (SPSS) software to run t-test as an independent sample test, to compare the expiration of non-pregnant and pregnant women in the second and third trimester depending on their: Peak Expiratory Flow (PEF), Forced Expiratory Flow (FEF25, FEF50, FEF75), Forced Expiratory Volume (FEV1), and Forced Vital Capacity (FVC). The research was carried out on sixty-five women who performed PFT to obtain their Spirometric parameters. The results showed the differences in flow-volume and volume-time curves between the non-pregnant and pregnant women, while the results of the SPSS software showed a significant difference (P<0.05) between these non-pregnant and pregnant women in the third trimester specifically.
