Taking a single Blood Pressure reading using an electronic home blood pressure cuff will provide a snapshot reading, which may or may not give a true account of the person’s blood pressure control. This is due to the fact that during the day, an individual’s blood pressure will vary according to physical, emotional, dietary and metabolic factors. 

Therefore, the average daily blood pressure is a more accurate means to determine whether or not a person’s blood pressure is within the normal range (non-diabetics: systolic pressure less than 140 mm Hg., diastolic less than 90 mm Hg.; diabetics: systolic pressure less than 130 mm Hg., diastolic less than 85 mm Hg.). This is accomplished by taking the average of two or three readings at different times of the day, over a period of one week. It is recommended that at each sitting, the blood pressure be measured two times, five to ten minutes apart, sitting quietly during the interval between the two. If the second pressure is markedly less than the first, take the average of those two readings. 

Individuals with abnormally high average blood pressure readings should consult with their physician regarding any potential investigations required as well as possible treatment.
