The cardiopulmonary changes among pregnant women were studied in 400 subjects (100 non-pregnant and 300 pregnant). The cardiovascular parameters measured are blood pressure (systolic and diastolic), pulse rate and mean arterial blood pressure by auscultatory method using stethoscope and sphygmomanometer. The pulmonary parameters measured are peak expiratory flow rate (PEFR), using Wright peak flow meter and respiratory rate the number times thoracic cage expands and relaxes. The cardiopulmonary parameters of pregnant women decreased significantly (p<.05) when compared to non-pregnant. The anthropometric parameters in first trimester when compared to the control group did not decrease significantly (P>0.05), while in second and third trimester the anthropometric parameters decreases significantly (p<.05) with positive correlation when compared to control. The cardiopulmonary parameters in pregnant women showed a significant changes (p<.05) when compare to non-pregnant.
