Ankle brachial pressure index (ABPI) calculations are performed by nurses in the assessment of patients with leg ulceration. The measurement of pressure in one arm alone can result in inaccuracy which may be clinically significant. Two vascular nurse technologists performed ABPI measurements on 250 patients with 487 lower limbs. Community nurses replicated the study on 71 patients, assessing 123 lower limbs. The study shows that 22% of patients in the vascular laboratory and 20% in the community had a difference in brachial pressures of > or = 15 mmHg, indicating the presence of arch vessel or upper limb arterial disease. Furthermore, 6% of patients in the laboratory and 2% in the community demonstrated that the difference in brachial pressures affected the ABPI calculation around the value of 0.8, thus potentially influencing their clinical management. ABPI measurements should be performed, taking both brachial pressures for optimum results.
护士在评估腿部溃疡患者时会进行踝臂压力指数（ABPI）计算。仅测量一侧手臂的血压可能会导致不准确，这在临床上可能具有重要意义。两名血管护士技术人员对250例患者的487条下肢进行了ABPI测量。社区护士对71例患者进行了重复研究，评估了123条下肢。研究表明，血管实验室中22%的患者和社区中20%的患者肱动脉血压差异≥15 mmHg，表明存在弓状血管或上肢动脉疾病。此外，实验室中6%的患者和社区中2%的患者表明，肱动脉血压差异影响了ABPI在0.8左右的计算，从而可能影响其临床管理。应测量双侧肱动脉血压以获得最佳结果来进行ABPI测量。
