What is this calculator?
Files today's pulse oximeter reading in a common discussion band. Home devices vary and cold fingers lie. This is a note, not A&E triage.
How it works
- Warm the finger, sit still, then type the reading.
- Read the band as a discussion label.
- How you feel, lips, and breathing still matter more than the meter.
Common questions
What is the oxygen saturation record keeper?
A band label for a number you already measured. Not a hospital monitor.
Is 94 percent an emergency?
It depends on you and how you feel. NHS advice often treats a sudden drop or feeling very unwell as urgent. Call 111 or 999 rather than refreshing this page.
Can I diagnose COVID or lung disease?
No.
