Pediatric Nocturnal Oximetry

Screening and diagnosis available everywhere in Quebec

What is a pediatric nocturnal oximetry?

Pediatric nocturnal oximetry is a simple, painless test done at home. It can help determine whether your child may be suffering from a sleep-related respiratory disorder by detecting decreased blood oxygen levels during sleep. Test results are used by your healthcare professionnel physician to decide whether your child should undergo a more thorough examination (e.g., polysomnography).

Night saturometry (oximetry) is a sleep apnea screening test offered exclusively to pediatric clients. This test is used to determine whether there is reduced oxygen in the blood during your child's sleep, and whether a more exhaustive diagnostic test should be recommended. Saturometry is performed at home, under your supervision. During your appointment, a sleep respiratory therapist will explain the steps for installing the sensor. The collected data is sent to a respirologist for analysis according to predefined medical criteria in order to determine the next steps.

Examination procedure

At Biron, we offer a 30-minute afternoon appointment with a respiratory therapist to explain how the device works and how to properly do the in-home test. We will ensure you have all the information you need for a successful diagnostic. The test will be conducted at home, during the night. The day after the test, we ask that you return the device to Biron's clinic by 11:00 a.m.


The results report for pediatric nocturnal oximetry will include an interpretative guide that can help the requesting health care professional direct the treatment in cases of suspected obstructive sleep apnea secondary to enlarged adenoids and/or tonsils.

This report will be sent to you and the requesting heath care professional by the method of your choice, either through the results portal or by mail, within 10 to 15 business days.

A medical prescription is required to perform this examination.
