Abstract

In the present study the partial pressure of carbon dioxide in arterial blood (PaC0:1 and respiratory rate (RR) were studied in pregnant and non-pregnant women in Dhaka city. Far this purpose a total 32 women for PaCO)and 100 women for RR with age ranging front 25 ...ears le 35 years without any recent history of respiratory diseases were selected. Normal pregnant women were taken as e.yperimental group and healthy nor-pregnant ...omen as return!. Data was collected during first trimester. second trimester and third trimester in pregnant women and also nompregnant women. The PaCOrwas determined by using 'EASY BLOOD GAS .0TO INALMER" and RR was recorded. The PaCO, and RR during different trimesters of pregnant .rumen were compared with that of non-pregnant 11.1101. Statistical analysis was drum with .tudents '1' rest. The PeCOr was significantly lower in first trimester, second trimester and third (rimester of pregnant women than that of non-pregnant women. Similarly, RR was significantly higher in first trimester. second trimester and third trimester of pregnant women than that of nonpregnant women. Again RR was significantly higher in third trimester than in first trimester and second trimester of pregnant women. There were no statistically significant difference of PaCO, among first trimester. second trimester and third trimester of pregnant women. Similarly, there were no statistically significant difference of RR between first trimester and second trimester of pregnant women. It may be concluded from the study that the progressively decreased PaCO• and increased RR throughout Me pregnancy were most likely MP be related to the effect of progesterone-induced hyperventilation. Hypermfilation in pregnancy is due to hypersensitivity of respiratory centre. Due to hyperventilation there is expel out of CO, miming decrease in PaC0r and increase in RR during pregnancy.
