Auscultatory mercury sphygmomanometers to measure blood pressure (BP) have been banned from health services because of risk of pollution and environmental accidents with mercury. Aneroid appliances could be an alternative.
To validate the Missouri aneroid device for blood pressure measurement in cancer patients according to the protocol of the European Society of Hypertension (ESH).
33 patients hospitalized or under outpatient care at the Cancer Institute of the State of São Paulo, FMUSP, were evaluated. Three trained and blinded observers performed nine sequential blood pressure measurements interspersed with the mercury sphygmomanometers. The differences between the values of systolic blood pressure (SBP) and diastolic blood pressure (DBP) of the test device with the mercury sphygmomanometer were classified according to the ESH protocol.
The Missouri equipment underwent all three phases required by the ESH Protocol for SBP and DBP, and it was approved in all of the phases. The average difference between the test device and the mercury sphygmomanometer was 0.62 (SD = 4.53) and 0.06 (SD = 6.57) mmHg for SBP and DBP, respectively. No association was found between the differences in BP measurements with sex, age, body mass index and arm circumference and length.
The results revealed that the aneroid Missouri device meets ESH accuracy recommendations for the measurement of SBP and DBP, and it can be used to replace the mercury sphygmomanometer.
听诊式水银血压计因存在汞污染和环境事故风险已被卫生服务机构禁用。无液血压计可能是一种替代选择。
根据欧洲高血压学会（ESH）的方案，对密苏里州无液血压计进行血压测量的验证，适用于癌症患者。
在圣保罗州癌症研究所，FMUSP，评估了 33 名住院或门诊治疗的患者。三名经过培训且盲法的观察者对九个连续血压测量进行了操作，每个测量之间穿插使用水银血压计。根据 ESH 方案，将测试设备与水银血压计的收缩压（SBP）和舒张压（DBP）值之间的差异进行分类。
密苏里州设备通过了 ESH 方案对 SBP 和 DBP 的所有三个阶段的要求，并且在所有阶段均获得通过。测试设备与水银血压计之间的 SBP 和 DBP 的平均差值分别为 0.62（SD=4.53）和 0.06（SD=6.57）mmHg。血压测量的差异与性别、年龄、体重指数和臂围及长度均无关联。
结果表明，无液血压计密苏里州设备符合 ESH 对 SBP 和 DBP 测量的准确性建议，可替代水银血压计。
