Oximetry

Oximetry is very safe.

Possible minor effects:

A small sensor is placed on your finger.
Light wavelengths pass through the tissue to estimate your oxygen saturation (SpO₂) and pulse rate.
Readings are taken within a few seconds.

Simple and painless: Oximetry is quick, non-invasive, and does not involve needles or breathing into equipment.
Movement matters: Keeping your hand still helps ensure an accurate reading.
Cold hands or nail products: Cold fingers, dark nail polish, or artificial nails can sometimes affect results—let staff know if this applies to you.
Temporary reading: Oximetry shows your oxygen level at that moment in time and does not explain the cause of low or high readings.
Interpretation: Results are reviewed alongside your symptoms and other tests, not on their own.
Reusable or disposable probes: Sensors are cleaned or single-use to maintain hygiene and safety.
