CNAP vs IABP in Pregnant Women With Placenta Accreta

The objective of this study is to investigate a technique to monitor blood pressure in women undergoing cesarean delivery with suspected placenta accreta spectrum. To achieve this objective, the investigators plan to conduct a prospective, observational study with the following aims: Specific Aim 1: Compare concordance between the systolic (SBP), diastolic (DBP), and mean arterial blood pressure (MAP) readings from the continuous non-invasive arterial blood pressure (CNAP) and IABP at several discrete points throughout the procedure Specific Aim 2: Determine the feasibility of using CNAP to aid in decision making by examining the parameters of volume responsiveness and arterial elastance at several discrete points throughout the procedure. The investigators hypothesize that the investigators can obtain similar blood pressure monitoring using CNAP as compared to the gold standard IABP in women undergoing cesarean delivery with suspected placenta accreta.
