To someone who may be suffering from obstructive sleep apnea (OSA), the two-night overnight/nocturnal polysomnogram (NPSG) plus continuous positive airway pressure (CPAP) Titration Study is considered the “gold standard” of sleep studies.
But what if, for some reason, you are unable to devote two nights at a sleep clinic? For example, an insurance provider may only choose to cover one night, leaving you to pay the full bill for the other. Or you may find it difficult to sleep in the unfamiliar environs of the sleep study center. Or other personal, financial, or work-related issues may make it difficult to commit to the two-day, non-contiguous window required for the NPSG/Titration studies.
