Abstract
Placental and endometrial partial pressures of oxygen (PO 2) were measured using a polarographic oxygen electrode during the first trimester of pregnancy. Between 8-10 weeks' gestation, placental PO 2 levels were significantly lower (P<. 001) than endometrial levels. A significant (P<. 001) increase was observed for placental PO 2 values measured at 12-13 weeks compared with those obtained at 8-10 weeks. We suggest that the increase of placental PO 2 at the end of the first trimester is related to the establishment of continuous maternal blood flow in the intervillous space.
