Oximetry is a test that measures your oxygen level and heart rate. This is part of the Obstructive Sleep Apnea (OSA) Screening process. When used overnight, a continuous measurement can be graphed. The patterns that are produced can assist in the diagnosing of Sleep Apnea.
Through this quick and easy test, a clinical diagnosis can be made by your physician. To be tested, IRS Independent Respiratory Services (IRS) requires a referral from your physician that can be faxed to 1-866-888-6011.
