The use of blood pressure cuffs containing bladders of appropriate size for the arm is a known prerequisite for correct blood pressure measurements. The Tricuff, containing three inflatable bladders of varying dimensions, one of which is automatically selected to fit the arm circumference, was compared to a standard cuff (12 x 35 cm) in 137 persons. In persons with large arms (circumference > or = 32 cm) measurement with the Tricuff showed on average 19.2 mm Hg lower systolic pressure and 12.9 mm Hg lower diastolic pressure than with the standard cuff. In persons with small arms (< 32 cm) the corresponding differences were 9.0 mm Hg and 7.5 mm Hg. Compared to the Tricuff, the standard cuff overestimates blood pressure in people with a large arm circumference. Overestimation may also be caused by the rubber bladder bulging more from below the standard soft nylon cuff than what the firmer texture of the Tricuff allows, resulting in falsely high values even in persons with normal arm circumference.
使用尺寸适合手臂的气囊式血压计袖带是正确测量血压的一个已知前提条件。将一种包含三个不同尺寸可充气气囊的三头袖带（其中一个气囊会自动选择以适配手臂周长）与标准袖带（12×35厘米）在137人身上进行了比较。在手臂较粗（周长≥32厘米）的人群中，使用三头袖带测量的收缩压平均比使用标准袖带低19.2毫米汞柱，舒张压平均低12.9毫米汞柱。在手臂较细（<32厘米）的人群中，相应的差值分别为9.0毫米汞柱和7.5毫米汞柱。与三头袖带相比，标准袖带会高估手臂周长较大人群的血压。高估也可能是由于橡胶气囊从标准软尼龙袖带下方鼓起的程度大于三头袖带更紧实质地所允许的程度，即使在手臂周长正常的人群中也会导致错误的高值。
