A 20 year old G1P0 female at 40 weeks of gestation presents to labor room with rupture of membranes and early onset of labor. She is extremely anxious with peripheral i.v placement and begins to Hyperventilate. If allowed to continue hyperventilation, It will cause
Hyperventilation → CO2 washout →Low PaCO2 levels → Vasoconstriction → Reduced placental perfusion
Decreased maternal arterial pH
Increased placental perfusion
Increased fetal arterial pH
Decreased maternal uterine artery flow
