Polysomnography (PSG) is a multi-parameter type of sleep study [1] and a diagnostic tool in sleep medicine.The test result is called a polysomnogram, also abbreviated PSG.The name is derived from Greek and Latin roots: the Greek πολύς (polus for "many, much", indicating many channels), the Latin somnus ("sleep"), and the Greek γράφειν (graphein, "to write").
The typical screening process for sleep apnea involves asking patients about common symptoms such as snoring, witnessed pauses in breathing during sleep and excessive daytime sleepiness. [19] There is a wide range in presenting symptoms in patients with sleep apnea, from being asymptomatic to falling asleep while driving. [19]
Obstructive sleep apnea (OSA) is the most common sleep-related breathing disorder and is characterized by recurrent episodes of complete or partial obstruction of the upper airway leading to reduced or absent breathing during sleep.
Doctors use this test to identify possible sleep disorders. A doctor may perform different types of sleep studies, and Medicare covers any of them when used to diagnose sleep apnea. It may also ...
The respiratory disturbance index (RDI)—or respiratory distress Index—is a formula used in reporting polysomnography (sleep study) findings. Like the apnea-hypopnea index (AHI), it reports on respiratory distress events during sleep, but unlike the AHI, it also includes respiratory-effort related arousals (RERAs). [1]
Apnea testing carries the risk of arrhythmias, worsening hemodynamic instability, or metabolic acidosis beyond the level of recovery and can potentially make the patient unsuitable for organ donation (see above). In this situation a confirmatory test is warranted as it is unsafe to perform the apnea test to the patient. [9]
