A disorder where breathing repeatedly stops and starts during sleep.
The evidence that matters most depends on which rating level applies to you. For a 0% rating, a sleep study or other record that documents sleep-disordered breathing is the key piece. For a 30% rating, medical records or provider notes describing persistent daytime hypersomnolence support that level, and your own statements about how excessive daytime sleepiness affects your work or daily activities can help show that the symptom is ongoing.
For a 50% rating, a prescription or records showing that a CPAP or other breathing assistance device has been prescribed and is in use are central. For a 100% rating, pulmonary function tests or arterial blood gas results showing carbon dioxide retention, imaging or clinical findings of cor pulmonale, or surgical records documenting a tracheostomy would reflect that level. Statements from you or those who know you about how your symptoms affect daily functioning can also help give VA a fuller picture of your condition at any level.
