Validation of TONOPORT V blood-pressure measuring monitor in adults.

A new automatic blood-pressure (BP) measuring device TONOPORT V was evaluated according to the International Protocol for Validation of Blood Pressure Measuring Devices in adults by the European Society of Hypertension. BP values measured by the TONOPORT V were compared to BP readings from two independent observers. A total of 33 patients (20 males, 13 females) provided systolic and diastolic BP readings in the normotensive, borderline hypertensive, and hypertensive range. Their age varied between 30 and 83 years, and their arm circumference between 23 and 36 cm. The device showed a mean (+/-s.d.) deviation from observer measurements of -0.7 (4.6) mmHg for systolic and -0.8 (4.4) 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.
