To evaluate the accuracy of the automated oscillometric upper-arm blood pressure (BP) monitor Globalcare GCE603 for home BP monitoring according to the International Protocol of the European Society of Hypertension (ESH) revision 2010.
BP was sequentially measured in 33 adult participants and compared with a standard mercury sphygmomanometer. A total of 99 comparison pairs were obtained and analyzed according to the ESH international protocol.
For the 33 eligible participants, the device achieved 80/99, 98/99 and 99/99 measurements of absolute differences between device and observers within 5, 10 and 15 mmHg for systolic BP (SBP) and 87/99, 98/99 and 99/99 for diastolic BP (DBP), respectively. The average device-observer difference was 1.01 ± 4.11 mmHg for SBP and −0.69 ± 3.56 mmHg for DBP, respectively. The number of participants with two or three of the device-observer difference within 5 mmHg was 28 for SBP and 30 for DBP, and there was no subject with none of the device-observer difference within 5 mmHg.
According to the validation results on the basis of the ESH international protocol revision 2010, the Globalcare GCE603 automated upper-arm BP monitor can be recommended for home measurement in general population.
