Investigational drug(s) / intervention(s)
Mean arterial pressure
Mean arterial pressure: Mean arterial pressure will be taken on the arm and on the ankle from the same patient and compared.
Study summary
This observational study aims to compare mean arterial pressure measurements obtained using an ankle blood pressure cuff with those obtained using a standard upper-arm cuff in pregnant individuals undergoing elective cesarean delivery under spinal anesthesia. The primary objective is to determine the level of agreement between the two measurement sites.The main question\[s\] it aims to answer \[is/are\]:
Demonstrate that the mean arterial pressure is similar between arm and ankle with the blood pressure cuff
Every participant will be their own control. (Measurements will be taken at both sites on every participant)

Primary outcome measure(s)
Comparison of mean arterial pressure taken by appropriately sized blood pressure cuffs between arm and ankle taken 5 min after birth. — From enrollment (in the waiting room) to end of surgery Comparison of mean arterial pressure taken by appropriately sized blood pressure cuffs between arm and ankle taken 5 min after birth. This is to measure the outcome at a time point compatible with skin-to-skin for the mother-baby dyad.
