Key result
The oscillometric method for blood pressure measurement has significant limitations and inaccuracies across various population groups, limiting the reliability of data interpretation.
Why the study?
The oscillometric method is increasingly replacing the traditional auscultatory method, but literature on its limitations remains limited.
Is the oscillometric method suitable and accurate for measuring blood pressure in all patient populations?
Is the oscillometric method suitable and accurate for measuring blood pressure in all patient populations?
The oscillometric method for blood pressure measurement has significant limitations and may be inaccurate in an expanding number of specific patient populations.

Oscillometric BP devices warrant interpretive caution in select patients; leaves open need for rigorous validation of maximum amplitude algorithms.
The oscillometric method, which is gradually replacing the traditional auscultatory method, is attractive to practitioner due to the possibility of automating blood pressure (BP) measurements. However, there is little literature information about its limitations. The purpose of this review is to address such issues. For this purpose, the main modern information on the maximum amplitude algorithm for BP measurement and location features, in which it is possible to obtain an oscillometric waveform, are preliminarily considered. In addition, the limitations and disadvantages of the method associated with both the equipment and the characteristics of various population groups are analyzed. The list of groups in which blood pressure measuring devices may be inaccurate has expanded significantly in the 2020s compared to the previous decade. This suggests that the reliability of the interpretation of data obtained by the oscillometric method in a certain part of patients is limited.

Posokhov et al. (2024) conducted a review in blood pressure measurement. Oscillometric method vs. auscultatory method was evaluated. The oscillometric method for blood pressure measurement has significant limitations and inaccuracies across various population groups, limiting the reliability of data interpretation.
