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 fully charge will need 2 hours. When the battery 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 line 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 use 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.

Measurement process

•  Press to power on the product and press again to start measuring blood pressure.
•  The product will automatically deflate the cuff slowly during the measurement, a typical measurement takes about 30s.
•  The blood pressure readings will scrolling appear in the product when the measurement finished.
•  The product will automatically release the cuff gas after the measurement is over.
•  Press the button to turn off the power after the measurement, then remove the cuff.
•  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 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 in. 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.

Measure ECG

Before using ECG

•  Before using 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.

Measurement process

• Press to power on the product and touch the electrodes to start measuring ECG. There are four methods for recording ECG by cablefree operation.
  • Method A: Lead I, right hand to left hand
  • Method B: Lead II, Right hand to left Leg
  • Method C: Lead II, right hand to left abdomen
  • Method D: Right hand to chest
• Keep touching electrodes gently for 30 seconds.
• When the bar if 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 (electromyograph) interference.
• The device can store maximum 10 records for ECG data. The oldest record will be overwritten when the 11th record is coming in. Please uploading data in time.

Turn on/off Heartbeat Sound
The buzzer beep when heartbeat is detected during ECG recording. You can turn on/off the heartbeat sound on the App.
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.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (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.

Note 1: At 80 MHz and 800 MHz, the separation distance for 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.

Annex Bland-Altman Plot of Blood Pressure
Note:

• The Bland-Altman Plots originated form clinical test, which data was gathered from pediatric /adult healthy volunteers in a controlled study.
• The clinical test applies for the device with the cuff size (22-42 cm) comparing with Mercury sphygmomanometer.
• The result met the criteria specified in ISO 81060-2:2013; In addition, there were no reported adverse effects during these investigations.
• Please refer to following for detail.

1. Figure 1. Plot of SBP difference between the paired blood pressure determinations against the reference systolic measurement
2. Figure 2. Plot of DBP difference between the paired blood pressure determinations against the reference diastolic measurement
