Overnight pulse oximetry

Overnight pulse oximetry is a non-invasive method that evaluates the patient’s blood oxygen levels using photoelectric methods while sleeping.

This oximetry test is performed at home using a finger oximeter, which should be placed on a part of the body that is relatively translucent and has good blood flow, for example, the fingers, toes or earlobe.

The study analyses the mean and minimum peripheral oxygen saturation, the oxygen desaturation index (ODI) and the minimum and maximum heart rate.

The OXIGEN salud staff will explain to the patient how the equipment works and how to place the oximeter before going to sleep.

After the study, the patient must schedule an appointment to return the equipment and transfer data. The report will be made on the basis of the automatic analysis and sent to the patient or prescribing medical staff.
