Answer

Currently, the only available tool for definitive diagnosis of obstructive sleep apnea is an overnight polysomnographic evaluation in the sleep laboratory. An overnight polysomnographic study usually includes multiple channels that aim to monitor sleep state, as well as cardiac and respiratory parameters (see the images below).

Nasopharyngoscopy or direct laryngoscopy and bronchoscopy may be required to determine anatomy prior to contemplated otolaryngologic surgery.
