The influence of auditory perception in measurement of blood pressure among specialist physicians

摘要

Assessment of blood pressure is one of the basics of physical examination usually performed by indirect auscultatorymethod using a mercury manometer. Several factors may cause observational error in assessment of blood pressure.Correct and reliable evaluation of blood pressure has a great role in diagnosis and treatment of diseases. So, the aim ofthe current study was to evaluate the role of auditory perception in measurement of blood pressure after excluding ormatching of other interventional factors. 70 specialists in Aria and 22 Bahman hospitals were enrolled in this study. 41cases were selected randomly using the table of randomized numbers by SPSS software. All cases underwent PTA andtympanometry in order to exclude those with hearing problems. A standard method for assessment of blood pressurewas explained for remaining cases and then they recorded the blood pressure of four patients and presented in a film.Each film was repeated 10 times in a randomized pattern so observers were compared with others and also themselves.According to the data significant differences was detected between observers. Mean interobservers standard error forsystolic blood pressure, diastolic blood pressure and mean blood pressure were 9.4, 20.5 and 16.1 mmHg,respectively. No significant difference detected in comparing observer’s recordings for each case by themselves. theseresults suggested it seems, independent of observers’ auditory perception can use as new method for assessment ofblood pressure.
