Arm and Finger Measurement for Blood Pressure Surveillance

Accurate blood pressure (BP) measurement is critical in peripartum care. The cuff and bladder sizes affects the accuracy of BP measurement. Current international BP measurement recommendations are based on mid-arm circumference (MAC). However, evidence have shown the discrepancies between these sizes, leading to inaccuracy of BP measurement. This study will measure arm and finger size of 300 parturients in third trimester to determine whether the MAC, finger measurement or body mass index (BMI) is the best clinical predictor for non-standard cuff sizes for BP measurement.
