•Supine hypotension syndrome can be corrected easily by having the woman turn onto her side (preferably the left side) to enhance blood flow through the vena cava. To increase the collateral blood circulation during pregnancy, teach the patient to rest on her left side rather than her back.
•When a pregnant woman lies supine, the weight of the growing fetus presses the vena cava against the vertebrae, obstructing blood flow from the lower extremities. This causes a decrease in blood return to the heart and decreased cardiac output and hypotension.
•Ambulation cannot relieve supine hypotension syndrome, however, it can stimulate circulation.
