6. Operation
6.1 Wearing the Device
Wear the wrist unit comfortably on your wrist. Place the finger sensor on your thumb or index finger. Ensure the sensor is snug but not too tight to avoid discomfort or restricted blood flow. The adjustable perimeter of the wristband is 16-23cm, and the probe cable length is approximately 22cm.


6.2 Starting Monitoring
Once properly worn, monitoring begins automatically. The device will display real-time SpO2 and heart rate readings. To wake the screen and view data, simply turn your wrist.
6.3 Real-Time Notifications
The OxyU can provide notifications if your blood oxygen level falls below a preset threshold. This threshold is customizable between 80% and 95% within the ViHealth app. Both the device and your connected phone will provide a reminder.


7. Data Management
7.1 App Data Synchronization
The OxyU stores up to 4 groups of data on the device, with each group capable of holding up to 10 hours of data. Data is automatically synchronized to the ViHealth app via Bluetooth when connected. It is recommended to upload data to the app promptly as the oldest data on the device will be overwritten by new recordings.

7.2 Viewing History and Detailed Data
Within the ViHealth app, you can view your history data in a list format. Click on any entry to see more detailed information, including trends for O2 score and lowest O2 over various periods (year, month, week).

Detailed views provide specific O2 and pulse rate data, including the amount of time spent with blood oxygen saturation below 90%.

7.3 PC Report Export
The ViHealth app offers a one-click export and sharing function for your data in PDF, CSV, or Binary formats. This allows you to manage and analyze your blood oxygen reports on a PC.
