Validation of TONOPORT V blood-pressure measuring monitor in adults

Abstract

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 (7s.d.) deviation from observer measurements of À0.7 (4.6) mmHg for systolic and À0.8 (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.

Cognitive Impairment Is Related to Increased Arterial Stiffness and Microvascular Damage in Patients With Never-Treated Essential Hypertension

“…Twenty-four hour ambulatory BP monitoring was carried out on the nondominant arm using the valid recorder TONOPORT V (General Electric, Health Care, Berlin, Germany) after validation of readings against a mercury sphygmomanometer by means of a Y tube. 16,17 The ambulatory BP monitoring device was set to obtain BP readings at 15 min intervals during the day (0700-2300) and at 20 min intervals during the night (2300-0700). The time of application and the type of the device were the same in all patients.…”

“…ABPM were performed annually (if applicable at least 4 weeks following a change in immunosuppression dosage) using the oscillometric Tonoport V device (GE Healthcare, Little Chalfont, Buckinghamshire, UK) (15). ABPM was included in analysis if at least 70% of all measurements were successful.…”

Prevalence of resistant hypertension and associated factors for blood pressure control status using Korean ambulatory blood pressure monitoring registry data

“…ABPM data were gathered as the form of raw data files uploaded to the study website. The device used in the study institute was all recommended as summarized in the website http://www.dableducational.org or passed the recommended validation protocols [ 7 ]. The raw data of ABPM were regarded as valid only when at least 14 readings of the awake blood pressure from 8AM to 9PM were available after omitting erroneous readings according to the following criteria [ 8 ]: pulse rate above 120 beats per minute systolic or diastolic blood pressure more than 25 mmHg above or below the previous and subsequent readings pulse pressure below 15 mmHg [ 9 ].…”
