Home Sleep Studies FAQ
What does a home study monitor?
Home sleep studies monitor airflow, oxygen saturation, respiratory effort, pulse, and snoring. We are able to look for apneas (complete blockages in the breathing) and hypopneas (partial blockages in the breathing). Unlike in-lab studies, we do not collect some information including sleep stages, sleep positions, carbon dioxide levels, and leg movements.
Is a home sleep study as good as an in-lab study?
About 80% of patients can be successfully diagnosed with a home study, and home studies are about 15% of the cost of an in-lab study.
An in-lab study allows us to collect more data than a home sleep study. Also, there may be some information misrepresented if you are awake for a large portion of the study. However, home studies often adequately diagnose obstructive sleep apnea. If a home sleep study comes back normal and we still suspect sleep apnea or another sleep disorder, we may ask you to return for an in-lab study.
In-lab studies are generally recommended for other conditions that affect oxygen and carbon dioxide levels such as chronic obstructive pulmonary disease (COPD) and heart failure.
What if there is not enough data?
If the study is too short or if there is too little data due to a sensor falling off, we will ask you to use the machine for another night to get an adequate study. If the study comes back normal and another study is recommended, your insurance may require two normal home studies before approving an in-lab study.
