What is a home sleep test (HST)?
A home sleep study is a modified sleep study that is performed in your home with a portable monitor. HST is used only to look for obstructive sleep apnea (OSA).
What is the difference between a Home Sleep Test and a sleep test performed in a Sleep Lab?
A home sleep test is performed in your home versus at a sleep lab. The portable monitoring device measures oxygen saturation, heart rate, air flow and effort. It will also record snoring and position.
A sleep test that is performed in a sleep lab will measure the above, but will additionally measure brain waves, sleep time and leg movements.
