This study is intended to calculate the core body temperature in patients who are having a Cesarean Section (C/S) and are kept warm with an Upper Body Forced Air Warming device (Bair Hugger) or underbody forced air warmer. These warming devices are approved and are a required item in many if not all surgical procedures. They are used daily throughout the hospital. The research question is: Where is the best place to position the warming blanket in pregnant mothers undergoing Cesarean section delivery. The researchers hope to compare post - operative core body temperatures in patients getting an Upper Body forced air device versus those getting an Underbody Body forced air warming device.
