Comparison of Auscultatory and Oscillometric Blood Pressure Measurements among School Children in Nigeria
Journal Title: International Journal of Medical and Health Sciences - Year 2018, Vol 7, Issue 2
Abstract
Objective: The aims of this study was to compare the blood pressure (BP) measurements using mercury sphygmomanometer and oscillometric device among Nigerian school children and examine the extent of their differences, if any. Patients and methods: A total of 1745 Nigerian school children were systematically recruited, each had two serial BP measurements done with mercury sphygmomanometer using „fourth report‟ guideline which were followed by two BP measurements using validated oscillometric device (Omron 705 IT®). Results: The oscillometric mean systolic BP, was significantly higher than the auscultatory (mercury) mean systolic BP (103.8 ± 11.0 mmHg vs. 98.7 ± 11.1 mmHg, p<0.001). The oscillometric mean diastolic BP was significantly higher than that of auscultatory (mercury) mean diastolic BP (61.3 ± 8.4 mmHg vs. 58.7 ± 9.0 mmHg, p<0.001). The differences in the mean BP measured by the two methods (oscillometric minus auscultatory) were 5.11 mmHg (95% CI, 4.61 to 5.61; p =<0.001), and 2.60 mmHg (95% CI, 2.11 to 3.10; p=<0.001) for systolic and diastolic BP respectively. Conclusion: The BP measured by the two methods are different, as the oscillometric method was significantly higher systolic and diastolic BPs compared with auscultatory method.
