Where do i find more information on cardiac output and pre-eclampsia?

Google it: I'm an internist, but from what i remember from med school, where i delivered 30 babies in 30 days at umdnj (1970), the cardiac output peaks at 7 months, and decreases thereafter. Pre-eclampsia is an abormal preg state where the mother develops severe high blood pressure and edema. Needs aggressive treatment, including lots of rest. But look for an obstetrician answer.
