ABSTRACT
Imparting concepts in ?ow dynamics of cardiovascular and respiratory physiology can be intimidating to the beginners in medical schools. We have tried to simplify the approach in effective transfer of these concepts using biophysical concepts and principles pertaining to functioning of these systems which help in easy understanding of the two vital systems in human body. Beginners in medical education ?nd it easy to relate to these concepts.
ABSTRACT
The study was conducted on 100 pregnant women in third trimester of uncomplicated pregnancy (Test group) and 100 age-matched non-pregnant women (Control group) in the age group of 25 to 35 years. Pulmonary function test parameters FVC, FEV1, PEFR and FEF25-75% recorded using Medspiror. The FEV1/FVC ratio was calculated. All parameters except FEV1/ FVC ratio were found to decline in the Test group as compared to the Control group. The decrease in FEV1 with pregnancy was not of such amplitude as decrease in FVC, and hence FEV1/FVC ratio was seen to increase. This study validates the physiological changes in pulmonary function brought by pregnancy and highlights the need to compile expected and accepted alterations in predicted values of PFT in comparison with the non gravid states for safer outcome of the pregnancy.
