Sleep Apnea Diagnosis Based on your medical history and an office examination, your doctor may recommend overnight observation in a sleep laboratory to confirm his or her suspicion of sleep apnea. A WatchPAT test may also be offered. Typically, during an overnight sleep study (called a polysomnogram or PSG) at a sleep lab, electrodes are placed on the body to record brain activity, eye movements, and muscle activity as you sleep. The sleep technician may place other sensors on your chest or near the nose to record your breathing patterns. Testing is usually performed in a private room at your normal bedtime and you are allowed to leave early the next morning. After your sleep data are analyzed, a report is sent to your physician.
