What it is
This is an overnight sleep study at a sleep center where a technologist records brain waves, breathing, oxygen and heart rhythm and starts CPAP or bilevel therapy to find the right pressure. It is used both for a full night of CPAP adjustment and for a split-night study that starts as a diagnostic study.
What the price covers
The hospital price usually covers the overnight study and the technologist. The sleep physician's interpretation is often billed separately, and the CPAP machine itself is bought separately.
