Comment s’équiper pour une oxymétrie ?
01. The oximeter
Before going to bed, place the oximeter on your non-dominant wrist and tighten the strap so that the device fits snugly against your wrist.
02. The cable
Insert the cable plug into the slot on the oximeter. The wire should go over the back of your hand.
03. The sensor
Insert the saturation sensor onto your index finger all the way to the tip. If possible, avoid nail polish.
04. The oximeter
The oximeter turns on and off automatically. Wear it on your wrist for the duration indicated by your sleep specialist.

The index finger or middle finger are the best fingers for placing an oximeter
Ambulatory oximetry
Oximetry alone is performed on an outpatient basis; it is a simple, non-invasive test. The patient picks up the oximeter at the center and returns it once the test has been performed at home.
It is a key diagnostic and monitoring tool in sleep medicine, particularly in tests such as respiratory polygraphy and polysomnography, where it is used to measure variations in oxygenation during the night.
Why is oximetry performed?
- Oximetry measures the oxygen level in the blood during sleep.
- This allows sleep apnea to be detected, when breathing stops briefly during the night.
- Identify drops in oxygen levels, which may indicate a sleep-disordered breathing condition
Comprendre les données d'une oxymétrie
- Normale : une saturation en oxygène entre 95 % et 100 %.
- Hypoxémie modérée : entre 90 % et 94 %, nécessitant une surveillance.
- Hypoxémie sévère : en dessous de 90 %, nécessitant une prise en charge par un spécialiste
