3.2.2  How to sit correctly

To take a measurement, you need to be relaxed and comfortably seated. Sit in a chair with your legs uncrossed and your feet flat on the floor. Place your left arm on a table so the cuff is level with your heart.

Viatom Blood Pressure Monitor BP2 & BP2A User Manual - How to sit correctly

Note:

  • The blood pressure can differ between the right arm and the left arm, and the measured blood pressure readings can be different. The Viatom recommends to always use the same arm for If the blood pressure readings between both arms differ substantially, check with your physician to determine as to which arm to use for your measurements.
  • The time is about 5s required for the product to warm from the minimum storage temperature between uses until the product is ready for its intended use when the ambient temperature is 20°C, and the time is about 5s required for the product to cool from the maximum storage temperature between uses until the product is ready for its intended use when the ambient temperature is 20° C.
3.2.3 Measurement process
  1. Press to power on the product and press again to start measuring blood pressure.
  2. The product will automatically deflate the cuff slowly during the measurement, a typical measurement takes about 30s.Viatom Blood Pressure Monitor BP2 & BP2A User Manual - The product will automatically deflate
  3. The blood pressure readings will scrolling appear in the product when the measurement finished.
Viatom Blood Pressure Monitor BP2 & BP2A User Manual - The blood pressure readings will scrolling appear
  1. The product will automatically release the cuff gas after the measurement is over
  2. Press the button to turn off the power after the measurement, then remove the cuff
  3. Press the memory button to review historical The blood pressure readings will appear in the product

Note:

  • The product has an automatic power shut-off function, which turns off the power automatically in one minute after measurement.
  • During the measurement, you should keep still and don’t squeeze the cuff. Stop measuring when the pressure result appear in the product. Otherwise the measurement may be effected and the blood pressure readings may be inaccurate
  • The device can store maximum 100 readings for Blood Pressure data. The oldest record will be overwritten when the 101th readings is coming Please uploading data in time.

NIBP Measurement Principle

The NIBP measurement way is oscillation method. Oscillation measurement is using automatic inflator pump. When the pressure is high enough to block arterial blood flow, then it would deflate slowly, and record all the change of cuff pressure in the deflation process to calculate blood pressure based on certain algorithm. The computer will judge whether the quality of signal is accurate enough. If the signal is not accurate enough (Such as sudden movement or touch of cuff while measurement), the machine will stop deflating or re-inflate, or abandon this measurement and calculation.

The operating steps needed to obtain accurate routine resting blood pressure measurements for the condition hypertension including:

— Patient position in normal use, including comfortably seated, legs uncrossed, feet flat on the floor, back and arm supported, middle of the cuff at the level of the right atrium of the heart.
— The patient should be relaxes much as possible and should not talk during the measurement procedure.
— 5 minutes should elapse before the first reading is taken.
— Operator position in normal use.

3.3  Measure ECG
3.3.1 Before using ECG

  • If the ECG electrodes are dirty, remove the dirt using a soft cloth or cotton bud dampened with disinfectant
  • During the measurement, do not touch your body with the hand with which you are taking the
  • Please note that there must be no skin contact between your right and left Otherwise, the measurement cannot be taken correctly.
  • Stay still during the measurement, do not speak and hold the product Movements of any kind will falsify the measurements.
  • If possible, take the measurement when sitting and not when
3.3.2 Measurement process
  1. Press to power on the product and touch the electrodes to start measuring

Viatom Blood Pressure Monitor BP2 & BP2A User Manual - Measurement process

Note:

  • Do not press the product too firmly against your skin, which may result in EMG (electromyograph) interference
  • The device can store maximum 10 records for ECG The oldest record will be overwritten when the 11th record is coming in. Please uploading data in time.

ECG Measurement Principle

The product collects the ECG data through the potential difference of the body surface through the ECG electrode, and obtains accurate ECG data after being amplified and filtered, then displays through the screen.

Irregular beat: If the change speed of heart rate exceeds a certain threshold during measurement, is judged as irregular heartbeat.

High HR: The heart rate > 120 /min

Low HR: The heart rate < 50 /min

If the measurement results do not meet the “Irregular beat”, “High HR” and “Low HR”, then judge the “Regular beat”.

3.4  Bluetooth

The product Bluetooth will be enabled automatically only when the screen lights up.

  1. Ensure the product screen is on to keep the product Bluetooth enabled.
  2. Make sure the phone Bluetooth is enabled.
  3. Select the product ID from the phone, then the product will be paired successfully with your phone
  4. You can export the measured data including SYS, DIS, ECG data to your phone

Note:

  • The Bluetooth technology is based on a radio link that offers fast and reliable data transmissions. The Bluetooth uses a license-free, globally available frequency range in the ISM band-intended to ensure communication compatibility worldwide.
  • The pairing and transmitting distance of wireless function is 1.5 meters in the normal. If the wireless communication is delay or failure between the phone and the product, you will try to narrow the distance between the phone and the product.
  • The product can pair and transmit with the phone under the wireless coexistence environment (e.g. microwaves, cell phones, routers, radios, electromagnetic anti-theft systems, and metal detectors), but other wireless product may still interface with pairing and transmission between the phone and the product under uncertain environment. If the phone and the product display inconsistent, you may need to change the

Is it true that associated apps have full administrative rights and functions on your PC and your network?

Yep. The app is just spyware.


Does it feed data to Apple Health?

I only have a android phone so can’t help you there. It does work well and repeats results. So far I like it


Larger cuff size

My arm is 16″ and there’s a few inches to spare.


What kind of cuff is it? Is it spring loaded, is the cuff automatic

It is a velcro cuff, full adjustable, and therefore comfortable, it is not spring loaded.
Once the cuff is fitted on the arm, pressing the button starts the automatic inflation and measurement cycle- ie it is fully automatic once the button is pressed.
