Study of respiratory rate TV, IC,& IRV in different trimesters of pregnancy.

Abstract

The anatomical, physiological and biochemical adaptations in pregnancy are profound. Many of these changes begin soon after fertilization and continue throughout the gestation and changes in the respiratory system are part of the same process. However there is insufficient information regarding the changes in respiratory parameters in different trimesters of pregnancy. Aims: The aim of the study was designed to evaluate the pulmonary function tests in 1st, 2nd and 3rd trimesters of pregnancy and compare them with non‑pregnant control group.
