Q

why does SVR increase during labor?

A

autotransfusions 300-500cc

labor causes SNS overdrive = increase constriction

blood is squeezed back into central circulation during contractions

larger tidal vol
smaller residual vol

36
Q

ph changes

A

compensated respiratory alkalosis

at placenta: more co2 exits fetal circ.
more co 2 exhealed per min

37
