A hallmark of sleep disordered breathing is the occurrence of arousals during sleep. Such arousals elicit generalized autonomic activation, which among other physiological changes, includes sympathetic nervous system-mediated peripheral vasoconstriction, and transient pulse rate elevation. The PAT technology allows measurement of these changes ...
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").

There are five main types of sleep studies that use different methods to test for different sleep characteristics and disorders.
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]
The main advantage is that these record in the usual sleep environment and thus are more representative of their natural sleep than staying overnight at a lab. Home sleep testing is more accessible and less expensive than polysomnography due to long waiting periods for in-lab tests, [45] and is increasingly being preferred by private insurance ...
The main reason for this development is the fact that, while retaining mobility, actigraphy offers reliable results with an accuracy that is close to those of polysomnography (above 90% for estimating total sleep time but dropping to 55% for a 4 - way sleep stage estimation problem). [14]
Sleep specialists measure the patient's sleep onset and offset, dim light melatonin onset, and evaluate Horne-Ostberg morningness-eveningness questionnaire results. Sleep specialists may also conduct a polysomnography test to rule out other sleep disorders like narcolepsy. Age and family history of the patient is also taken into consideration. [2]
