Using the Product

Charge the Battery

Use the USB cable to charge the product. Connect the USB cable to a USB charger or to the PC. A full charge will need 2 hours. When the battery is charged fully the indicator will be blue.

The product works in a very low power consumption and one charge usually works for months. On-screen battery symbols which indicate the battery status can be seen on the screen.

Note: The product cannot be used during charging, and if choosing a third-party charging adaptor, select one that complies with IEC60950 or IEC60601-1.

Measure Blood Pressure

Applying the arm cuff

1. Wrap the cuff around the upper arm, about 1 to 2 cm above the inside of the elbow, as shown.
2. Place the cuff directly against the skin, as clothing may cause a faint pulse and result in a measurement error.
3. Constriction of the upper arm, caused by rolling up a shirtsleeve, may prevent accurate readings.
4. Confirm that the artery position mark is lined up with the artery.

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.

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 using the same arm for measurement. 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.Viatom Blood Pressure Monitor

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.
3. The blood pressure readings will scroll to appear in the product when the measurement is finished.
4. The product will automatically release the cuff gas after the measurement is over.
5. Press the button to turn off the power after the measurement, then remove the cuff.
6. Press the memory button to review historical data. 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 one minute after measurement.
• During the measurement, you should keep still and don’t squeeze the cuff. Stop measuring when the pressure result appears in the product. Otherwise, the measurement may be affected and the blood pressure readings may be inaccurate.
• The device can store a maximum of 100 readings for Blood Pressure data. The oldest record will be overwritten when the 101st readings are coming in. Please upload data in time.Viatom Blood Pressure Monitor

NIBP Measurement Principle

The NIBP measurement way is the oscillation method. Oscillation measurement is using an automatic inflator pump. When the pressure is high enough to block arterial blood flow, then it would deflate slowly, and record all the changes in cuff pressure in the deflation process to calculate blood pressure based on a certain algorithm. The computer will judge whether the quality of the signal is accurate enough. If the signal is not accurate enough (Such as sudden movement or touch of the cuff while measuring), 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 include:

• 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 relaxed 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.

Measure ECG

Before using ECG

• Before using the ECG function, pay attention to the following points in order to obtain precise measurements.
• The ECG electrode must be positioned directly against the skin.
• If your skin or hands are dry, moisten them using a damp cloth before taking the measurement.
• If the ECG electrodes are dirty, remove the dirt using a soft cloth or cotton bud dampened with disinfectant alcohol.
• During the measurement, do not touch your body with the hand with which you are taking the measurement.
• Please note that there must be no skin contact between your right and left hand. Otherwise, the measurement cannot be taken correctly.
• Stay still during the measurement, do not speak, and hold the product still. Movements of any kind will falsify the measurements.
• If possible, take the measurement when sitting and not when standing.Viatom Blood Pressure Monitor

Measurement process

1. Press to power on the product and touch the electrodes to start measuring ECG.
   • Method A: Lead I, right hand to left hand
   • Method B: Lead II, right hand to left abdomen
2. Keep touching electrodes gently for 30 seconds.
3. When the bar is fully filled, the product will show the measurement result.
4. Press the memory button to review historical data.

Note:

• Do not press the product too firmly against your skin, which may result in EMG (electromyography) interference.Viatom Blood Pressure Monitor
• The device can store a maximum of 10 records of ECG data. The oldest record will be overwritten when the 11th record is coming in. Please upload 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 in speed of heart rate exceeds a certain threshold during measurement, is judged as an 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”.

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’s 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, and ECG data to your phone.

Note:

• The Bluetooth technology is based on a radio link that offers fast and reliable data transmissions.
  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 the wireless function is 1.5 meters in the normal. If the wireless communication is delayed or fails 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 products may still interface with pairing and transmission between the phone and the product under uncertain environment. If the phone and the product display are inconsistent, you may need to change the environment.Viatom Blood Pressure Monitor
