Table 4 Blood pressure measurement using auscultation method

From: 2013 Korean Society of Hypertension guidelines for the management of hypertension: part I–epidemiology and diagnosis of hypertension

Standard Procedures of Blood Pressure Measurement
After resting for 5 or more minutes in a quiet, appropriate environment
Avoiding smoking, alcohol, or caffeine before measurement
Measuring 2 or more times at 1- to 2-min intervals in one visit
A cuff with a bladder at least 40% of arm circumference wide; 80% to 10% of arm circumference long (a standard bladder for adults: 13 cm wide; 22 to 24 cm long)
Maintaining the upper arm cuff at the heart level
Inflating the cuff rapidly and deflating slowly at a speed of 2 mm Hg per heart beat
Identifying the blood pressure as the systolic blood pressure at the first Korotkoff sound; the blood pressure as the diastolic blood pressure at the fifth Korotkoff sound
Regarding the blood pressure as the diastolic blood pressure at the fourth Korotkoff sound in pregnancy, arteriovenous shunt, and chronic aortic insufficiency
Taking blood pressure in both arms on the initial visit; subsequently using the arm of higher pressure for measuring blood pressure
Taking blood pressure in legs to exclude peripheral arterial disease, when pulses in the lower extremities are weak
Repeating the measurement three or more times to estimate the average systolic and diastolic pressure in case of arrhythmia
Measuring BP after 1- and 3-min standing in elderly persons and persons with diabetes and suspected orthostatic hypotension
