Nowadays, a hypertension becomes the common disease and accounts for larger percentage of interest in the medical academic field. One of the most common blood pressure measurement technique is the non-invasive method. When a larger cuff is used by comparing to the upper-arm circumference of the subject, the blood pressure is measured lower than expected. Conversely, the value obtained by it is higher than normal case if a smaller cuff size is used. In this experimental study, 400 pairs of simultaneous blood pressure measurements on 50 subjects were obtained by the auscultatory and the oscillometric methods respectively by using three kinds of cuff sizes(Small, Medium and Large). Experimental identification for blood pressure differences due to the cuff size was proceeded. Also, cuff size standard for Korean was presented to obtain more accurate blood pressure according to the arm circumferences. As the result of this study, the selection of the appropriate cuff size was found to be very important because the main factors influencing the accuracy of the oscillometric blood pressure measurement was the cuff size by depending on the arm circumference of the subject.
