In recovery or chronic care, it offers a practical way to track trends over time, supporting conversations with healthcare professionals. While it’s a powerful consumer tool, remember readings are estimates; factors such as skin pigmentation can influence measurements. Establishing a personal baseline when healthy and at rest is recommended, and consult a licensed healthcare provider to interpret readings in context.\u003c\/p\u003e \u003ch2\u003eImportant usage notes\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003eAlways place the finger fully into the sensor and stay still during measurement for best results.\u003c\/li\u003e \u003cli\u003eConsider your baseline SpO2 and PR values when interpreting readings, especially if you have darker skin pigmentation or melanin-related variations.
