Blood Pressure Information

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.

WHO Blood Pressure Classification Indicator
The DBP-8297B is equipped with a classification indicator based on established guidelines from the World Health Organization. The chart below (color coded on monitor unit) indicates test results.: Blood Pressure Classification Indicator

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.

Blood Pressure Q＆A

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:

Improper cuff placement
Make sure cuff is snug-not too tight or too loose.
Improper body position
Make sure to keep your body in an upright position.
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.

Recommended separation distances between portable and mobile RF communications equipment and the device

The device is intended for use in an electromagnetic environment in which radiated therefore disturbances are controlled. The customer or the user of the device can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the device as recommended below, according to the maximum output power of the communications equipment.
Rated maximum output power of transmitter

W

| Separation distance according to frequency of transmitter m
80 MHz to 800 MHz| 800 MHz to 2.7 GHz
0.01| 0.12| 0.23
0.1| 0.38| 0.73
1| 1.2| 2.3
10| 3.8| 7.3
100| 12| 23
For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres (m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.

NOTE1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.

NOTE2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
