Set custom thresholds for your SPO2 levels. If your oxygen drops below your set safety line (e.g., 92%), the app can trigger an audible alert, ensuring you take immediate action.
The waveform looks flat or noisy. Solution: Check the Perfusion Index (PI). If PI < 0.5%, warm your hands by rubbing them together. Cold fingers restrict blood flow, giving false low SpO2 readings. spo2 assistant 31 free
