What is a normal oxygen level for older adults?

A pulse oximeter clips on your finger and estimates how much oxygen your blood is carrying (SpO2). Most healthy adults, including older adults, read 95% or higher. Some people with lung conditions have a lower personal target set by their clinician.

Getting an accurate reading

• Rest for a few minutes and keep your hand warm and still, below heart level.
• Remove nail polish or artificial nails on that finger.
• Wait for the number to settle, then record it.
• The FDA notes oximeters can be less accurate on darker skin tones — watch for symptoms, not just the number.

When to seek care

• Call your provider if readings stay at 92% or lower, or keep dropping.
• Get emergency help for trouble breathing, bluish lips or face, chest pain, or new confusion — whatever the number says.
