The sleep disorder assessment along with a clinical evaluation will provide a guide for your risk of Obstructive Sleep Apnea (OSA). If sleep apnea is suspected, at-home overnight tests are then recommended to evaluate whether you experience apneas during the night, which are associated with drop in blood oxygen levels.
The sleep apnea tests are typically scored and interpreted by specially trained professionals who have the expertise to understand the meaning of the sleep data gathered and to ascertain your correct diagnosis. Typically your sleep disorder specialist will explain your results to you and help you understand if you have sleep apnea, and if so, whether it is mild, moderate or severe. They will normally recommend further at-home testing if required or treatment using an oral device or mouthpiece.
