[. . . ] When the heart relaxes between heartbeats, the lowest blood pressure is diastolic pressure. The mean arterial pressure (MAP) is the average pressure that forces blood through the arteries. It is not the average of the systolic and diastolic blood pressure; rather, MAP corresponds to a state of balance between the compressive and expansive forces acting on the arterial wall when there is no distension outward or inward. MAP is an excellent way to evaluate the stress on the walls of your blood vessels, and can be used to evaluate excessive load on the cardiovascular system. Show your MAP history to your doctor to provide additional information that may help him or her understand your situation. Blood pressure measurement can highly reflect one's health condition. High blood pressure is potentially linked to serious illnesses such as stroke, heart disease and kidney failure. Since there is no symptom most of the time, many hypertensive 4 people do not realize they are at risk until their health is seriously threatened. What is the standard blood pressure classification?The following chart (Figure 3) was taken from the World Health Organization (WHO), and describes the various classifications. NOTE · Hypotension value is for reference only. · Blood pressure is considered high when either the diastolic or systolic blood pressure value exceeds the normal range. · Only a physician can tell you your normal blood pressure range and the point at which you are at risk. Consult your physician to obtain these values. If the measurements taken with this product fall outside the range, consult your physician. Hypertension 95 Hypertonia (Border value) 90 Hypotension (low pressure) systolic 140-159 diastolic 90-94 Normal range diastolic under 89 90 Systolic (mmHg) Figure 3 5 140 160 systolic over 160 Why does my blood pressure fluctuate throughout the day?Individual blood pressure varies greatly both on a daily and a seasonal or temperature basis. These variations may be more pronounced in hypertensive patients. Normally the blood pressure rises while at work and is at its lowest during sleep. Figure 4 below illustrates the variations over a single day with measurement taken every five minutes. The rises in blood pressure at 4 PM (A in the graph) and 12AM (B in the graph) correspond to an attack of pain and sexual intercourse (Beven, Honour & Stott, Clin. 36:329, 1969). 160 140 A B BLOOD PRESSURE 120 (mmHg) 100 80 60 40 20 12 13 14 15 16 17 18 19 20 21 22 23 24 1 2 3 4 5 6 7 8 (high pressure) diastolic over 95 Sleep 9 10 11 PM Time AM Figure 4 diastolic (mmHg) systolic under 90 systolic under 139 HOW THE BLOOD PRESSURE MONITOR WORKS This product uses the Oscillometric Measuring method to detect your blood pressure.
