Comparability of oscillometric to simultaneous auscultatory blood pressure measurement in children
Blood Pressure Monitoring Mar 15, 2019
Ringrose JS, et al. - In 20 children aged 2-12 years recruited from a tertiary-care Pediatric Nephrology Clinic, oscillometric waveforms were recorded and oscillometric blood pressure (BP) was derived using two standard algorithms (fixed-ratio and slope-based algorithms). Researchers compared the findings to simultaneous auscultation. They obtained 2 oscillometric and auscultatory BP readings, measured simultaneously, 30–60 s apart. Females comprised 40% of the study population. Hypertension or a history of hypertension was present in 50% of participants. Compared to simultaneous auscultatory BP in children aged 2-11, a difference by more than 5 mmHg in either systolic BP or diastolic BP was observed in oscillometric BP derived using two commonly used algorithms. More understanding of the functionality and accuracy of oscillometry in children is required.
