Do not confuse self-monitoring with self-diagnosis. Blood pressure measurements should only be interpreted by a health professional who is familiar with your medical history. 2. Contact your physician if test results regularly indicate abnormal readings. 3. If you are taking medication, consult with your physician to determine the most appropriate time to measure your blood pressure. NEVER change a prescribed medication without first consulting with your physician. 4. Individuals with serious circulation problems may experience discomfort. Consult your physician prior to use. 5. For persons with irregular or unstable circulation resulting from diabetes, liver disease, arteriosclerosis or other medical conditions, there may be variations in blood pressure values measured at the wrist versus at the upper arm. Monitoring the trends in your blood pressure taken at either the arm or the wrist is nevertheless useful and important. 6. People suffering from vascular constriction, liver disorders or diabetes, people with cardiac pacemakers or a weak pulse, and women who are pregnant should consult their physician before measuring their blood pressure themselves. Different values may be obtained due to their condition. 7. People suffering from arrhythmias such as atrial or ventricular premature beats or atrial fibrillation only use this blood pressure monitor in consultation with your doctor. In certain cases oscillometric measurement method can produce incorrect readings. 8.Too frequent measurements can cause injury to the patient due to blood flow interference. 9.The cuff should not be applied over a wound as this can cause further injury. 2 Safety Notice Thank you for purchasing the DBP-8297B Blood Pressure Monitor.

Blood Pressure Information 33 Blood Pressure Information 34 Blood Pressure Blood pressure is the force of blood pushing against the walls of arteries. It is typically measured in millimeters of mercury

(mmHg.) Systolic blood pressure is the maximum 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. 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 blood pressure. If these measuring numbers become too high, it means the heart is working harder than it should. Upper curve : systolic blood pressure Lower curve: diastolic blood pressure g H m m 200 150 100 50 WHO Blood Pressure Classification Indicator The DBP-8297B is equipped with a classification indicator based on established guidelines from the World Health Organization.

Blood Pressure Classification Indicator Blood Pressure Information 35 Blood Pressure Information 36 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. By maintaining a healthy lifestyle and visiting your physician on a regular basis, hypertension and relative diseases are much easier to control when diagnosed in the early stages. 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. Systolic

( mmHg ) Blood Pressure QA 37 Blood Pressure QA 38 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 medical environment. This is known as White Coat Hypertension and may be caused by feeling anxious or nervous. Note: Abnormal test results may be caused by:

1. Improper cuff placement Make sure cuff is snug-not too tight or too loose. 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 wrist? What is the difference?

A: Either wrist can be used when testing, however, when comparing results, the same wrist should be used. Testing on your left wrist may provide more accurate results as it is 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. Maintenance 39 Maintenance 40 1. Avoid dropping, slamming, or throwing the unit. 3. When cleaning the unit, use a soft fabric and lightly wipe with mild detergent. Use a damp cloth to remove dirt and excess detergent. 2. Avoid extreme temperatures. Do not use outdoors. 4.

Blood Pressure Information 33 Blood Pressure Information 34 Blood Pressure Blood pressure is the force of blood pushing against the walls of arteries. It is typically measured in millimeters of mercury

(mmHg.) Systolic blood pressure is the maximum 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. 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 blood pressure. If these measuring numbers become too high, it means the heart is working harder than it should. Upper curve : systolic blood pressure Lower curve: diastolic blood pressure g H m m 200 150 100 50 WHO Blood Pressure Classification Indicator The DBP-8299B is equipped with a classification indicator based on established guidelines from the World Health Organization.

Blood Pressure Classification Indicator Blood Pressure Information 35 Blood Pressure Information 36 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. By maintaining a healthy lifestyle and visiting your physician on a regular basis, hypertension and relative diseases are much easier to control when diagnosed in the early stages. 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.

( mmHg ) Blood Pressure QA 37 Blood Pressure QA 38 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 medical environment. This is known as White Coat Hypertension and may be caused by feeling anxious or nervous. Note: Abnormal test results may be caused by:

1. Improper cuff placement Make sure cuff is snug-not too tight or too loose. 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 wrist? What is the difference?

A: Either wrist can be used when testing, however, when comparing results, the same wrist should be used. Testing on your left wrist may provide more accurate results as it is 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. Maintenance 39 Maintenance 40 1. Avoid dropping, slamming, or throwing the unit. 3. When cleaning the unit, use a soft fabric and lightly wipe with mild detergent. Use a damp cloth to remove dirt and excess detergent. 2. Avoid extreme temperatures. Do not use outdoors. 4.
