The data were in accordance with criterion 1 of the ANSI/AAMI/ISO 81060– 2:2013 standard requirements (≤ 5 ± ≤ 8 mmHg). In addition, the mean device-observer difference in the 85 participants was − 2.7 ± 5.89 mmHg for SBP and − 3.3 ± 4.99 mmHg for DBP, fulfilling criterion 2 with a standard deviation of ≤ 6.39 mmHg for SBP and ≤ 6.09 mmHg for DBP.Conclusion: The OMRON HEM-1040 BP monitor fulfilled the requirements of the ANSI/AAMI/ISO validation standard.Keywords: blood pressure monitoring device, accuracy, protocol, standard, validation
