Validation of the PhysioQuant blood pressure measuring monitor in adults.

A new automatic blood pressure (BP) measuring device PhysioQuant (also marketed under the brand name Ergoscan) was evaluated according to the International Protocol for Validation of Blood Pressure Measuring Devices in adults issued by the European Society of Hypertension. BP values measured by the PhysioQuant were compared with BP readings from two independent observers. Thirty-three patients (13 male, 20 female) provided systolic and diastolic BP readings in the normotensive, borderline hypertensive, and hypertensive range. Their age varied between 29 and 93 years, their arm circumference between 23.5 and 37 cm. The device showed a mean (+/-SD) deviation from observer measurements of -0.1 (+/-3.4) mmHg for systolic and +1.1 (+/-3.9) mmHg for diastolic BP. The accuracy of the device did not vary according to BP values or other patient characteristics. The device passed all phases of the protocol and can be recommended following the regulation rules of the European Society of Hypertension.
