TL;DR
Its utility for diagnosing SAHS was evaluated by a single night nocturnal home oximetry test followed by a conventional polysomnographic study and it was found that the interpretation of the Sao 2 recording based on the presence of repetitive fluctuations in the Sao 1 signal should improve its accuracy as a test for detecting SAHS.
Abstract
A negative home oximetry test result is helpful in ruling out the diagnosis of SAHS in patients clinically suspected of having this syndrome, because a negative test result reduced the probability from 54.1% to 3.1% in our patients. However, a positive oximetry test increased the probability from 46% to 61.4% in our group of patients.
