Your doctor ordered an overnight sleep study (also called a polysomnogram or PSG) either in a sleep center or your home, to determine if you have sleep apnea. After you complete the sleep study, your doctor will give you the results and discuss what to do next.
You may be given a copy of your sleep study report. The report is going to include information on how you slept such as: how long you slept, your Apnea Hypopnea Index (AHI) or how many times you stopped or partially stopped breathing and if your oxygen is saturated. The defining numbers of OSA are based upon your AHI. Alternatively, if your numbers fluctuate between sleeping on your side versus on your back, you may havePositional Sleep Apnea (POSA), defined as AHIsupine ≥ 2 x AHInon-supine.2
