Describe the utero-placental circulation and the principles of placental physiology as related to placental gas exchange and regulation of placental blood flow.
Pregnant women have normal peripheral sympathetic nervous system activity. TRUE/FALSE
Uterine blood flow in the non pregnant state is 700mL/min. TRUE/FALSE
Increased maternal systemic resistance can lead to increased placental blood flow at term. TRUE/FALSE
A “normal” blood pressure reading in a supine (term) pregnant woman’s arm is a reliable indicator of uterine perfusion pressure. TRUE/FALSE
If there is no maternal hypotension then neuraxial blockade does not alter uterine blood flow. TRUE/FALSE
