Polysomnography (PSG) is often ordered by physician when one is suspected to have Sleep Apnea. Neurologist also will order PSG to screen for neurological diseases such as Periodic Limb Movement (PLM). It is often done during the night time but it depends on the patient’s normal sleeping time. At least four hours of sleep data is needed in order to assess whether one has sleep apnea and its severity. There are mainly two types of PSG studies: Partial PSG or Full PSG. Partial PSG involves only the record of respiratory signals whereas full PSG also record neurology signals and ECG. Partial PSG is often used as a screening tool. Patients who are in the risk group or showing some symptoms of Sleep Apnea are put into a partial PSG study. The doctor will be able to confirm the Sleep Apnea and suggest the severity of the condition from the analysis of the Partial PSG. Partial PSG is often a portable study that can be done either at patient’s home or some in hospital settings. Full PSG is ordered when the patient is in a high risk group or when the doctor wants to confirm the type of apnea so that they can prescribe the right treatment. Some Full PSG are done to exclude certain type of neurology diseases. Full PSG is often a stationary study that must be done in hospital sleep laboratory. Cost of the Full PSG is normally higher than a Partial PSG.
Welcome to the Sleep Apnea Club~!
I've been very lucky for having a chance to understand what sleep apnea is and how bad it could affect one's life. I've seen people who are so exhausted, having poor quality of life and being very unproductive because they are too tired to do almost everything!
