Validation of the TONOPORT VI ambulatory blood pressure monitor in adults according to the European Society of Hypertension International Protocol revision 2010

Abstract

The present study aims to examine the performance of the TONOPORT VI ambulatory blood pressure (BP) monitor in the inflation and deflation measurement methods, according to the European Society of Hypertension International Protocol revision 2010 (ESH-IP 2010). Systolic and diastolic blood pressures (SBP and DBP, respectively) of 33 subjects (23 female, 10 male) were sequentially measured and compared with reference measurements obtained by two observers using a standard mercury sphygmomanometer. The subjects were selected according to the recruitment instructions of the ESH-IP 2010. Three comparative readings were performed per subject. Among the 99 readings in the inflation measurement method were 92/94 (SBP/DBP) with differences ⩽5, 97/99 ⩽10 and 98/99 ⩽15 mm Hg. All of the 33 subjects had at least 2 out of 3 comparative readings with differences ⩽5 mm Hg and 0/0 of the subjects had no reading ⩽15 mm Hg. The validation of the deflation measurement method resulted in differences where 93/91 were ⩽5, 98/98 were ⩽10, and 99/99 were ⩽15 mm Hg. Thirty-two of the 33 subjects had at least 2 out of 3 comparative readings ⩽5 mm Hg and 0/0 of the subjects had no reading ⩽15 mm Hg. In conclusion, the TONOPORT VI, respectively, in the inflation and deflation measurement methods met all requirements of Part 1 and 2 of the ESH-IP 2010. Based on the study results, the TONOPORT VI can be recommended for BP measurements in adults.
