Correlation of patient characteristics with arm and finger measurements in Asian parturients: A preliminary study

Accurate blood pressure (BP) measurement depends on appropriate cuff size and shape in relation to the arm. Arm dimensions outside the recommended range of cuff sizes or trunco-conical arms may result in inaccurate BP measurements. Measuring BP using finger cuffs is a potential solution. Arm cuff size is based on midarm circumference (MAC), and trunco-conicity is quantified by conicity index.
