What is an in-lab sleep study?
You should consider taking a Polysomnography (PSG) if you’ve been prescribed an in-lab sleep test by your doctor, if you hope to meet one of our sleep specialists so you can do the test, or if the results of your home respiratory polygraph always comes up normal but your doctor suspects the presence of another sleep disorder.
This test can determine the source of your sleeping problems and can ensure that you have received the proper diagnosis regarding a sleep disorder. It is the gold standard in sleep testing and provides more information than other test like the home respiratory polygraph (HRP).
Just like the HPR, it will record multiple physiological parameters such as airflow, thoracic and/or abdominal effort, heart rate, body position and oxygen saturation of the blood. Furthermore, the PSG monitors the cerebral activity (EEG), cardiac activity (ECG), muscle activity or skeletal muscle activation (EMG) and eye movement (EOG).
