Abstract

Introduction: In clinical practice BP measurements are increasingly being taken by automatic devices, most of which use the oscillometric method (B). Varied international recommendations were introduced to minimalize discrepancies between BP taken by mercury sphygmomanometers (A) and automatic devices (B). Though, it still remains unknown whether results obtained by these two methods vary during changes in posture. In this study lower body negative pressure (LBNP) stimulus was used to induce changes in blood distribution similar to these occurring while changing position from lying to standing. Thus, during the whole experiment BP measurements were taken in the same - supine position. Aim: To compare values of BP recorded by auscultatory (A) and oscillometric (B) method during application of LBNP and see if they differ significantly. Materials and methods: 23 healthy 19-year-old men had BP measured by both instruments; on one arm by the mercury sphygmomanometer Diplomat Presameter - Riester, on the other by oscillometric device HPM 100 - Temed at 2 minutes intervals during LBNP changing from 0 to -15 and from 0 to -40 mm Hg. Differences (Δ) between BP values recorded by method A and B during the experiment were analysed. Results: There were no differences between values recorded for the systolic blood pressure (SBP) at rest (LBNP=0 mm Hg) and when different LBNP was applied. On the contrary, when diastolic blood pressure (DBP) was measured, significantly lower values was recorded at LBNP -15 and -40 mm Hg (Δ/-15 mm Hg=2.0±5.8 mm Hg, Δ/-40 mm Hg=1.9±5.3 mm Hg versus initial rest values Δ/0 mm Hg=6.7±7.6 mm Hg; p
