Level 1 sleep study
In-Lab Sleep Testing
A Level 1 sleep study is the most detailed sleep test available. You spend the night in a sleep laboratory while a sleep scientist monitors your study in real time.
Overview
A Level 1 study records brain activity, eye and muscle movements, breathing, oxygen levels, heart rhythm, leg movements and body position, with video and a scientist watching throughout the night. Because the study is attended, sensors can be adjusted and any events noted as they happen.
In-lab studies are used when a home study is not suitable, when the diagnosis is unclear, or to find the right CPAP pressure under supervision. Studies take place at [LAB LOCATION].

- Significant heart, lung or neuromuscular conditions
