Comparative StudyComparison of the oscillometric blood pressure monitor (BPM-100(Beta) ) with the auscultatory mercury sphygmomanometer.
To compare directly the accuracy of the BPM-100(Beta) monitor (an automated oscillometric blood pressure device) with standard auscultatory mercury sphygmomanometry. ⋯ The BPM-100(Beta) is an accurate blood pressure monitor for the office setting, meeting all requirements of the Association for the Advancement of Medical Instrumentation and achieving an 'A' grade according to the British Hypertension Society protocol.

A simulation-based evaluation of nine oscillometric blood pressure monitors for self-measurement.
To evaluate the performance of nine self-measurement oscillometric blood pressure monitors using a simulator. ⋯ The nine monitors in general performed differently with respect to the simulator. The results cannot be used fully to reflect the monitors' performance on human subjects because they were not based on clinical evaluation. Studies that lead to a more realistic simulation of oscillometric blood pressure are needed. Protocols integrating both clinical and simulation-based evaluations need to be developed.

Randomized Controlled Trial Comparative Study Clinical Trial Controlled Clinical TrialA cross-over evaluation of different methods and devices to measure blood pressure in type 1 diabetic patients with nephropathy.
In type 1 diabetic patients with nephropathy, tight blood pressure control has been shown to prevent the progression of the disease. Up until now, self-monitoring, ambulatory and office blood pressure values have not been compared in these patients. Thus, we have evaluated blood pressure values obtained in the office by a physician and at home by self-monitoring with those measured under ambulatory conditions in these patients. Additionally, for blood pressure self-monitoring, three different devices (the sphygmomanometer, upper-arm oscillometer and wrist oscillometer) were compared. ⋯ Office blood pressure measurements may over-estimate blood pressure in patients with type 1 diabetes and diabetic nephropathy. Because the oscillometric wrist device tends to over-estimate diastolic values, upper-arm devices should be preferred for blood pressure self-monitoring in these patients.

Randomized Controlled Trial Comparative Study Clinical TrialOptimizing cuff width for noninvasive measurement of blood pressure.
It is well established that indirect measurements of blood pressure made with a standard 13cm-wide cuff are erroneously high for large arms and low for small arms. To correct for this error, the American Heart Association recommends adjusting cuff width to 40% of the arm's circumference. ⋯ The optimum cuff width for the indirect measurement of blood pressure is not directly proportional to arm circumference, but is proportional to the logarithm of the arm's circumference.
