Important Information on Blood Pressure and its Measurement

  1. How does high or low blood pressure arise?
    • Your level of blood pressure is determined in the circulatory center of the brain and adjusts to a variety of situations through feedback from the nervous system. To adjust blood pressure, the strength and speed of the heart (Pulse), as well as the width of circulatory blood vessels is altered.Blood vessel width is controlled by fine muscles in the blood vessel walls.
    • Your level of arterial blood pressure changes periodically during heart activity: During the “blood ejection” (Systole) the value is highest (systolic blood pressure value). At the end of the heart’s “rest period” (Diastole) pressure is lowest (diastolic blood pressure value).
  2.  Which values are normal?
    • Please refer to the diagram below(Picture-01)
    • Diastolic bloodJamr-B21H-B21HT-Blood-Pressure-Monitor- \(1\)
    • There are six grids in the display of device. Please refer to the picture-01-01. Different grids represent different interval scales of WHO.Jamr-B21H-B21HT-Blood-Pressure-Monitor- \(2\)

Measurement Procedure

  • Before measurement:

    • Avoid eating and smoking as well as all forms of exertion directly before measurement. These factors influence the measurement result. Find time to relax by sitting in an armchair in a quiet atmosphere for about ten minutes before taking a measurement.
    • Remove any garment that fits closely to your upper arm.
    • Always measure on the same arm (normally left).
    • Always compare measurements taken at the same time of day, since blood pressure changes during the course of the day, as much as 20-40 mmHg.
  • Fitting the Cuff
    Please refer to picture-04

    • The cuff is preformed for easier use. Remove tight or bulky clothing from your upper arm.
    • Wrap the cuff around your upper left arm. The rubber tube should be on the inside of your arm extending downward to your hand. Make certain the cuff lies approximately 2to3 cm) above the elbow. Important! The on the edge of the cuff (Artery Mark) must lie over the artery which runs down the inner side of the arm.
    • To secure the cuff, wrap it around your arm and press the hook and loop closure together.
    • There should be little free space between your arm and the cuff. You should be able to fit 2 fingers between your arm and the cuff. Cuffs that don’t fit properly result in false measurement values. Measure your arm circumference if you are not sure of proper fit.
    • Lay your arm on a table (palm upward) so the cuff is at the same height as your heart. Make sure the tube is not kinked.
    • Remain seated quietly for at least two minutes before you begin the  measurement.

  • Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey, should be less than the compliance level in each frequency range.

  • Interference may occur in the vicinity of equipment marked with the following symbol:

  • NOTE 1  At 80 MHz and 800 MHz, the higher frequency range applies.

  • NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.

  • A  Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the device is used exceeds the applicable RF compliance level above, the device should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the device.

  • B   Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

  • For some services, only the uplink frequencies are included.
  • The carrier shall be modulated using a 50% duty cycle square wave signal.
  • As an alternative to FM modulation. 50% pulse modulation at 18 Hz may be used because while it does not represent actual modulation, it would be worst case.

|

  • The MANUFACTURER should consider reducing the minimum separation distance, based on RISK MANAGEMENT, and using higher IMMUNITY TEST LEVELS that are appropriate for the reduced minimum separation distance. Minimum separation distances for higher IMMUNITY TEST LEVELS shall be calculated using the following equation:
  • Where P is the maximum power in W, d is the minimum separation distance in m, and E is the IMMUNITY
  • TEST LEVEL in V/m.
