It is typically measured in millimeters of mercury (mmHg.) Systolic blood pressure is the maximum indicates test results. force exerted against blood vessel walls each time the heart beats. Diastolic blood pressure is the force exerted on blood vessels when the heart is resting between beats. WHO Blood Pressure Classification Indicator The DBP-6277B is equipped with a classification indicator based on established guidelines from the World Health Organization. The chart below (color coded on monitor unit) An individual's blood pressure frequently changes throughout the course of a day. Excitement and tension can cause blood pressure to rise, while drinking alcohol and bathing can lower blood pressure. Certain hormones like adrenaline (which your body releases under stress) can cause blood vessels to constrict, leading to a rise in If these measuring numbers become too high, it means the heart is working harder Upper curve : systolic blood pressure Lower curve: diastolic blood pressure blood pressure. than it should. g H m m 200 150 100 50 6 1 2 1 8 2 4 Time of day Example: fluctuation within a day (male, 35 years old) Severe Hypertension Moderate Hypertension Mild Hypertension High-n ormal Normal Optimal mmHg Normal BP Bluetooth SMART AM PUL

Blood Pressure Classification Indicator Blood Pressure Information 25 Blood Pressure Q&A 26 Health Reminder Hypertension is a dangerous disease that can affect the quality of life. It can lead to a lot of problems including heart failure, kidney failure, and cerebral hemorrhaging. Q: What is the difference between measuring blood pressure at home or at a professional healthcare clinic?

A: Blood pressure readings taken at home are now seen to give a more accurate account as they better reflect your daily life. Readings can be elevated when taken in a clinical or By maintaining a healthy lifestyle and visiting your physician on a regular basis, medical environment. This is known as White Coat Hypertension and may be caused by hypertension and relative diseases are much easier to control when diagnosed in their feeling anxious or nervous. early stages. Systolic

( mmHg ) Severe Hypertension Moderate Hypertension Mild Hypertension High-normal 180 160 140 130 120 Normal Optimal Note: Abnormal test results may be caused by:

1. Improper cuff placement Make sure cuff is snug-not too tight or too loose. Make sure bottom of the cuff is approximately 1-2cm (1/2'') above the elbow joint. 2. Improper body position Make sure to keep your body in an upright position. 3. Feeling anxious or nervous Take 2-3 deep breaths, wait a few minutes and resume testing. Q: What causes different readings?

A: Blood pressure varies throughout the course of a day. Many factors including diet, stress, cuff placement, etc. may affect an individual's blood pressure. Q: Should I apply the cuff to the left or right arm? What is the difference?

A: Either arm can be used when testing, however, when comparing results, the same arm should be used. Testing on your left arm may provide more accurate results as it is 80 85 90 100 110 Diastolic

( mmHg ) located closer to your heart. Q: What is the best time of day for testing?

A: Morning time or any time you feel relaxed and stress free. Note: Do not be alarmed if an abnormal reading occurs. A better indication of an individual's blood pressure occurs after 2-3 readings are taken at the same time each day over an extended period of time. Consult your physician if test results remain abnormal. Maintenance 27 Maintenance 28 1. Avoid dropping, slamming, or throwing the unit. 4. Cuff Cleaning and Disinfection:
