Home sleep testing (HST) is an increasingly popular way to diagnose obstructive sleep apnea (and in some cases, screen for other sleep disorders) remotely. As opposed to spending the night in a sleep lab, the patient is able to self-administer an HST from the comfort of their own home at a lower price than in-lab sleep testing. They may also conveniently undergo multiple nights of home sleep testing, or use an HST as a long-term sleep monitor. But HSTs also have limitations, including only being clinically appropriate for patients who meet specific pre-test criteria. This comparison guide compares HST devices on parameters including price, rental/leasing options, type, maximum channels, power, chain-of-custody, warranty, dimensions, memory, and recording time.
