04 spo2

The SpO2 Trends screen on the Healthypi Move provides users with real-time insights into their blood oxygen levels.

When NOT to measure SpO2

Avoid measuring while walking, shaking, or if the user is shivering. Excessive motion can interfere with the sensor’s accuracy.
Cold extremities or restricted blood flow may prevent the device from detecting proper signals.
After Physical Activity allow a few minutes for your body to return to a resting state after exercise before taking a measurement.
Ensure the device is adequately charged. Low battery levels may affect sensor performance and data transmission.
Excessive sweat or dense hair beneath the watch body may interfere with the SpO2 sensor’s ability to obtain accurate readings. Ensure the skin is dry and clean, and consider repositioning the device if needed.
Do not attempt for PPG streaming while the device is charging, as this may introduce electrical interference into the signal.

Wear the HealthyPi Move at least two finger-widths above the wrist bone. This position provides a more stable surface and better contact with the skin, as the area is generally wider than directly over the wrist bone—leading to more accurate sensor readings.
Tap on the Measure SpO2 button on the device. The measurement process will begin automatically.

If the device is unable to receive a proper and stable PPG (photoplethysmogram) signal within the allotted time, an error message will be displayed.

When a stable PPG signal is received, the device will display the SpO2 value along with a timestamp, indicating a successful measurement.
