In patients with obesity, it was determined what proportion had an arm slant angle (SA) < 83° and which measure best predicted arm conicity. Patient experience with noninvasive blood pressure measurement was evaluated.
Arm SA was calculated from arm measurements. Linear regression determined whether BMI, weight, or right midarm circumference (MAC) best predicted conicity. Patient experiences were evaluated by survey and conventional content analysis of free-text comments.
One hundred participants had a median (interquartile range; range) BMI of 44.1 (39.1-53.1; 31.1-80.8). Thirty-three (33%) had a right arm SA < 83°. Seven (7%) had a right MAC outside the recommended range. BMI, weight, and the right MAC showed low correlation with and explained little of the variation (with age and sex adjustment) in right arm SA (r = -0.29, -0.27, -0.31; P = 0.003, 0.007, 0.002; R = 0.09, 0.08, 0.10). Forty-two (42%) reported noninvasive blood pressure measurement caused severe pain, and 30 (30%) reported skin damage. Themes identified in free-text responses were "problems with equipment," "feelings and experiences," and "concerns about accuracy."
Current equipment is inadequate for patients with obesity based on MAC and conicity. Pain and skin damage contributed to negative experiences of these patients.
在肥胖患者中，确定有多大比例的人手臂倾斜角度（SA）<83°，以及哪种测量方法最能预测手臂的锥形度。评估患者对非侵入性血压测量的体验。
从手臂测量值计算手臂 SA。线性回归确定 BMI、体重或右中臂周长（MAC）哪个能最好地预测锥形度。通过调查和对自由文本评论的常规内容分析评估患者的体验。
100 名参与者的 BMI 中位数（四分位距；范围）为 44.1（39.1-53.1；31.1-80.8）。33 人（33%）的右臂 SA < 83°。7 人（7%）的右臂 MAC 超出推荐范围。BMI、体重和右臂 MAC 与右臂 SA 的相关性较低，并且（经年龄和性别调整后）仅能解释很小一部分的变异性（r = -0.29、-0.27、-0.31；P = 0.003、0.007、0.002；R = 0.09、0.08、0.10）。42 人（42%）报告非侵入性血压测量引起严重疼痛，30 人（30%）报告皮肤损伤。自由文本回复中确定的主题为“设备问题”、“感觉和体验”以及“对准确性的担忧”。
根据 MAC 和锥形度，目前的设备不适合肥胖患者。疼痛和皮肤损伤导致这些患者的体验不佳。
