Measure
All Participants
All patients who agree to participate in the study will have the Masimo Rainbow Pulse CO-Oximeter non-invasive hemoglobin monitor placed on their finger during cesarean delivery. A CBC will be drawn immediately prior to delivery and this value will be compared to the values obtained from the monitor. The patients will be separated into quartiles based on total drop in hemoglobin (pre-op to post-op day 1) and the values from the monitor compared between quartiles. Masimo Rainbow Pulse CO-oximeter: Masimo Rainbow Pulse CO-oximeter will be used to measure hemoglobin values of pregnant women during primary cesarean delivery

PRIMARY outcome

Timeframe: 1 day post partum

Population: This value was compared to post operative day 1 hemoglobin from a complete blood count testing. We used Pearson correlation analysis. range of values from +1 to -1. A value of 0 indicates that there is no association between the two variables. A value greater than 0 indicates a positive association;
