Background, relevance, and practical use
Normal oxygen saturation (SpO2) is typically listed as 95% to 100%. At sea level in healthy adults. This is most useful as a reference point rather than a one-size-fits-all answer: it helps you quickly sanity-check numbers and avoid unit or magnitude mistakes.
In practice, this constant is used as a screening and interpretation reference. A good workflow is to start with this baseline, then adjust for context (measurement method, precision needs, and real-world conditions). That gives you speed without sacrificing accuracy.
If you need high precision, verify the source standard and units before final calculations. For most day-to-day use, this value is reliable for estimation, explanation, and quick comparisons.
