Real Fuzzy Measuring Technology

This unit uses the oscillometric method to detect your blood pressure. Before the cuff starts inflating, the device will establish a baseline cuff pressure equivalent to the air pressure. This unit will determine the appropriate inflation level based on pressure oscillations, followed by cuff deflation. 
During the deflation, the device will detect the amplitude and slope of the pressure oscillations and thereby determine for you the systolic blood pressure, diastolic blood pressure, and pulse.

Blood Pressure Standard

The National High Blood Pressure Education Program Coordinating Committee has developed a blood pressure standard, classifying blood pressure ranges into 4 stages. (Ref. The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure-Complete Report JNC-7, 2004). This blood pressure classification are based on historical data, and may not be directly applicable to any particular patient. It is important that you consult with your physician regularly. Your physician will tell you your normal blood pressure range as well as the point at which you will be considered at risk. For reliable monitoring and reference of blood pressure, keeping long- term records is recommended. Please download the blood pressure log at www.rossmaxhealth.com 

Blood Pressure Fluctuation

Blood pressure fluctuates all the time!
You should not be overly worried if you encounter two or three measurements at high levels. Blood pressure changes over the month and even throughout the day. It is also influenced by season and temperature.

6. This cuff is suitable for your use if the arrow falls within the solid color line as shown on the right (Fig. 7). If the arrow falls outside the solid color line, you will need a cuff with other circumferences. Contact your local dealer for additional size cuffs.

Measurement Procedures

Here are a few helpful tips to help you obtain more accurate readings:

• Blood pressure changes with every heartbeat and is in constant fluctuation throughout the day.
• Blood pressure recording can be affected by the position of the user, his or her physiological condition and other factors. For greatest accuracy, wait one hour after exercising, bathing, eating, drinking beverages with alcohol or caffeine, or smoking to measure blood pressure.
• Before measurement, it’s suggested that you sit quietly for at least 5 minutes as measurement taken during a relaxed state will have greater accuracy. You should not be physically tired or exhausted while taking a measurement.
• Do not take measurements if you are under stress or tension.
• During measurement, do not talk or move your arm or hand muscles.
• Take your blood pressure at normal body temperature. If you are feeling cold or hot, wait a while before taking a measurement.
  If the monitor is stored at very low temperature (near freezing), have it placed at a warm location for at least one hour before using it.
• Wait 5 minutes before taking the next measurement.
  1. Press the ON/OFF/START key. All displays will appear for approxi-mately one second before returning to “0”.
  2. The unit will automatically inflate to the appropriate inflation level based on the user’s pulse oscillations. Measurement will then be-gin. It is important to remain still and quiet during measurement. Any significant movement may affect measurment results.
  3. When the measurement is completed, systolic, diastolic and pulse will be shown simultaneously and be saved automatically in memory system. Up to 90 memories can be saved.
  4. Measurement is now completed. Press the ON/OFF/START key to turn off the power. If no key is pressed, the unit will shut off automatically in 1 minute.
     This monitor will re-inflate automatically to approximately 220 mmHg if the system detects that your body needs more pressure to measure your blood pressure.
     Note: This monitor automatically switches off approximately 1 minute after last key operation.
     • To interrupt the measurement, simply press the Memory or ON/OFF/START key; the cuff will deflate immediately.
     • During the measurement, do not talk or move your arm or hand muscles.
