BACKGROUND: The accuracy of oscillometric blood pressure (BP) measuring devices determined in resting conditions may be distorted in those under hemodialysis (HD). METHODS: The evaluation of accuracy of the Omron HEM-907 was performed in accordance with the International Protocol for validation of BP measuring devices (IP). Out of a group of 49 patients with end-stage renal disease (ESRD) (56.7 +/- 15.6 years), four groups of 33 patients each were selected to ascertain their BP before and after HD. RESULTS: The Omron HEM-907 fulfilled the IP accuracy requirements for systolic BP measurements before and after HD. In the case of diastolic BP before HD, the Omron HEM-907 did not fulfill both requirements for phase 2.2 IP. In only 21 out of 33 patients, the difference between the mean of two observers and the Omron HEM-907 device (Diff) was not more than 5 mmHg, while the requirement was 22 patients. In seven patients, all three Diff were over 5 mmHg, while the accepted limit is three. After HD, the Omron HEM-907 did not fulfill one out of two criteria of phase 2.2 IP - in five people, all three Diff were over 5 mmHg. CONCLUSION: The Omron HEM-907 oscillometric method of BP measurement should not be used to measure BP before and after HD in ESRD patients. In ESRD patients, an alternative method of BP measurement, in the event of a lack of a mercury sphygmomanometer, could be a classical auscultatory method together with the Omron HEM-907, which allows for this type of BP measurement.
