Measure you upper arm at a point mid way between your elbow and shoulder. The cuff on the DS1902PV monitor will fit arm circumferences between 9” and 17”. Most people will fit within this range. If you're arm size is greater than 17” your monitor will give readings that are higher than actual.

The DS-400PV monitor comes with two (2) cuffs; the Med. cuff fits arms from 9” to 13” in circumference. The Large cuff fits arms from 13” to 17”.
The wrist monitor fits wrists between 5” an 8.5” .

All of the Prevention blood pressure monitors use the oscillometric method of measuring blood pressure. Each time your heart beats it causes a surge of blood to flow through your arteries. When the cuff of the monitor is applied against your artery and inflated, this surge can be detected by a special sensor as a very small change in cuff pressure. The monitor applies a specialized mathematical algorithm to the information it collects during the measurement cycle to derive your diastolic and systolic pressure values and displays them on the digital display. Unlike the mercury column or aneroid gauge commonly used in your doctors office, an oscillometric monitor does not need a stethoscope to listen to the pumping sounds.

Your blood pressure is constantly changing throughout the day. It can even vary over a period ofjust a few minutes. So you should not think of a specific number for your blood pressure. The World Health Organization (WHO) developed the following blood pressure classification. This is only a general guideline, you should consult your physician to determine what is optimum for you.

You may be suffering “white coat hypertension’, where you experience elevated readings while at your doctors office. It may also be a perfectly normal variation. Your blood pressure is not a static number; rather it varies throughout the day. You're blood pressure is also affected by normal daily activities such as eating, drinking caffeine, physical activity or anxiety. These can cause your blood pressure to change quite a bit. Try taking your blood pressure at around the same time each day after resting comfortably for 5 – 10 minutes in a quiet place. You can also bring your monitor along to your next visit and have the nurse or doctor do some comparison measurements. Take several reading with both methods for comparison. Because of the different methods used, the first measurement should be taken with your monitor.

Don’t take a measurement immediately after physical activity or during stressful times. You should rest comfortably in a quiet place for 5 minutes prior to your measurement.
Avoid eating, smoking or drinking , especially caffeine, for at least 30 minutes before your readings.

The process of taking your blood pressure causes constriction of your arteries. By waiting between readings, the arteries are allowed to return to their normal condition. It is recommended that you wait at least 5 minutes between readings.

The flashing heart icon means that the monitor detected an irregular pulse rhythm during the measurement process. This can be caused by something a simple as body movement or talking during the measurement. If it is displayed frequently and you have remained still and silent during the measuring process, it may be an indication of an irregular pulse or arrhythmia, a potentially serious condition. You should consult with your doctor.

Moving or talking during the measurement will cause you to get this type of error code. You should remain still and quite during measurement.

Your blood pressure is not a static value and can be different each time you take it. It can be affected by many things including exercise, movement during measurement, talking, eating, smoking, drinking(especially caffeine) or a full bladder. You should try to take your blood pressure at around the same time each day, first thing in the morning and again in the evening. Rest for about 5 minutes before measuring and use correct posture; seated with your back supported and feet flat on the floor.

The preferred posture is seated at a table in a straight backed chair with your feet flat on the floor. Using an arm cuff, make sure the cuff is located properly on the upper arm and the forearm is extended naturally and supported by the table. Do not tense your arm or clench your fist.
If you are using a wrist cuff, raise your hand across your chest with your fingers extended toward your opposite shoulder. This will place the monitor at approximately the center of your chest at the height of your heart. Keep your arm and hand relaxed.
Do not talk or move during measurement.

The monitor can work properly with the cuff placed over a light weight shirt or sweater. If you roll or push up a sleeve make sure it is not restricting circulation in your upper arm as this can prevent getting an accurate reading.
