Rectangular cuffs and bladders are currently used for blood pressure (BP) measurement at the upper arm. However, large arms always have a tronco-conical shape. Aim of this study was to ascertain whether rectangular and tronco-conical cuffs provide different readings in obese subjects with very large arms. In obese people, the upper arm has a pronounced tronco-conical shape and rectangular cuffs may overestimate BP. Tronco-conical cuffs should be used for BP measurement in subjects with very large arms.

Abstract
Rectangular cuffs and bladders are currently used for blood pressure (BP) measurement at the upper arm. However, large arms always have a tronco-conical shape. Aim of this study was to ascertain whether rectangular and tronco-conical cuffs provide different readings in obese subjects with very large arms. In obese people, the upper arm has a pronounced tronco-conical shape and rectangular cuffs may overestimate BP. Tronco-conical cuffs should be used for BP measurement in subjects with very large arms.
