Who may be able to join
AI generated eligibility summary. Written by an AI model from the official source data and checked on a sample basis. It can contain mistakes, so confirm anything important against the original source. How we use AI
Who might be able to join this trial:
- Adults aged 18 or older who have been referred to a sleep laboratory at a university hospital for a sleep study to investigate suspected obstructive sleep apnea (a condition where breathing repeatedly stops during sleep).
Who may not be able to join:
- People currently taking blood-thinning medications (anticoagulants).
- People who have a condition that causes abnormal bleeding or affects blood clotting.
- People whose blood oxygen level at rest while awake is below 88% as measured by a pulse oximeter.
- People who do not agree to take part in the study.
- People who are not fully alert and oriented (a standard alertness score below 15 out of 15).
- People whose sleep study results do not meet the quality standards required for interpretation, as set by the American Academy of Sleep Medicine.
- People whose sleep study was done more than 15 days before the sensory test; in most cases, the sensory test is done the same day as or the day after the sleep study.
- People whose sleep study shows that more than 5% of their breathing pauses during sleep originate from the brain (central apneas) rather than from a physical airway blockage.
- People with a history of surgery on the jaw, face, or throat area.
- People with a known cancer affecting the throat or voice box area.
- People who have had brain or spinal surgery within the last three months, or whose surgery has left lasting neurological effects.
- People who have had a traumatic brain injury in the last three months, or more than three months ago if it has left lasting neurological effects.
- People with an active neuromuscular disease affecting the muscles of the head and neck, or with lasting effects from such a disease present at the time of testing.
- People with a history of stroke or other blood vessel disease affecting the brain.
- People with diabetes.
- People who regularly take oral corticosteroids (such as prednisone) at a dose of 20 mg per day or more, or an equivalent dose of another corticosteroid.
- People who have had an upper respiratory tract infection (such as a cold) within the 15 days before testing.
