The sleep disorder assessment domain in South America is experiencing a pronounced shift toward Home Sleep Testing (HST) solutions, driven primarily by the need for cost-effectiveness and increased accessibility. While in-lab Polysomnography (PSG) remains the gold standard, HST devices (often Type III or IV) offer a significantly cheaper, more convenient alternative for the initial diagnosis of uncomplicated OSA in high-probability patients.

HST is particularly well-suited to the geographical and economic realities of South America. It eliminates the need for patients to travel long distances to specialized sleep centers, which are often concentrated in major cities. This allows testing to reach populations in rural or underserved areas, increasing overall diagnostic capacity without requiring massive investment in new physical laboratories.

The convenience of testing in one's own bed leads to better patient compliance and a more accurate representation of typical sleep patterns, further solidifying HST's role as a vital screening and diagnostic tool. This flexible, remote model is key to scaling diagnostic services efficiently across the diverse region.
