Why the study?
Variations in arm circumference and cuff sizes cause different pressure readings, prompting the need for an adjustment factor to compare readings across any combination.
Does changing the arm circumference coverage by a sphygmomanometer cuff alter blood pressure readings in healthy adults?

May support cuff coverage adjustment in BP measurement; hypothesis-generating and requires larger validation before practice change.
Does changing the arm circumference coverage by a sphygmomanometer cuff alter blood pressure readings in healthy adults?
A 1% decrease in upper arm circumference coverage by a blood pressure cuff leads to a 1 mmHg increase in both systolic and diastolic pressure readings, allowing for a standardized adjustment factor.
Reischl et al. (2022) studied this question.
