[Accuracy of double stethoscope device for blood pressure evaluation]

ABSTRACT

Blood pressure [BP] is routinely evaluated intermittently during the clinical status for care and treatment. The most common method to measure BP is by using the sphygmomanometer with a stethoscope. This method may be difficult for medical students that will use BP for medical evaluation. The purpose of this study was to compare the accuracy of double stethoscope device for blood pressure monitoring, with standard ausculatory measurements using a mercury sphygmomanometer. In this distinguished report, 65 volunteer participants were studied. Means, standard deviations and Systolic, Diastolic pressure were calculated. The correlation between groups was determined with Pearson correlation. Mean difference in systolic, Diastolic Blood pressure between standard and routine method with double stethoscope method measurements, was not significant [P<0.001] and were in agreement with Pearson correlation between them. This study demonstrates that the double stethoscope device provides an accurate measure of blood pressure that is closely approximates with what is achieved by the indirect auscultator method, using a mercury sphygmomanometer
