STUDY OF THE DIFFERENCES IN THE ARTERIAL BLOOD PRESSURE VALUES IN HEALTHY PEOPLE MEASURED SIMULTANEOUSLY ON LEFT AND RIGHT ARMS

Arterial blood pressure measurement constitutes a fundamental aspect of nursing practice. The clinical significance of this measurement lies in its ability to assess systolic and diastolic blood pressure, which serve as crucial indicators of cardiovascular health and significant predictors of cardiovascular events. The purpose of the study is to investigate the difference in arterial pressure values after simultaneous measurement of the left and right arm in healthy people. Materials and methods. Data from 160 volunteers, including 125 healthy individuals (men and women), were analyzed. The mean age of the participants was 38.72±12.134 years, with 54 (43.2%) male and 71 (56.8%) female participants. Results. The subjects demonstrated normal blood pressure values. Statistically significant differences were found between systolic pressure (SBP) of the right and left arm (p=0.05), between diastolic pressure (DBP) of the right and left arm (p=0.05), as well as a difference in measurements between men and women. Absolute differences in systolic blood pressure between the two arms in healthy subjects were 2.184 ± 8.960 mmHg at (t |124| = 2,726, p =0.007). The mean absolute difference between the two diastolic values was 0.880 ± 6.474 mmHg at (t|124|= 1.520, p=0.1315), respectively. The influence of various risk factors on these differences has been established. A relationship was established with gender, age, alcohol use, smoking, weight (BMI). Conclusions. No significant disparity was observed between bilateral systolic blood pressure measurements in healthy individuals. The findings indicate a minimal difference in arterial pressure measured simultaneously in both arms of healthy subjects (5 mmHg). However, these results are reliable and may serve as an indicator of heightened cardiovascular risk.
