Comparison of Non-Invasive Mean Arterial Blood Pressure Measurements at the Arm and Ankle During Elective Cesarean Delivery.
Observational Study Comparing Non-Invasive Mean Arterial Blood Pressure Measurements at the Arm and Ankle During Elective Cesarean Delivery to Facilitate Skin-to-Skin Contact.
St. Justine's Hospital
110 participants

OBSERVATIONAL
Conditions
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)
