A normal result in polysomnography shows normal results for all parameters (EEG, ECG, blood pressure, eye movement, air flow, pulse oximetry, etc.) monitored throughout all stages of sleep.
Once the test is over, the monitors are detached from the patient. No special measures need to be taken after polysomnography.
