Upper Airway Resistance Syndrome

What is UARS (Upper Airway Resistance Syndrome)?

UARS is very similar to Obstructive Sleep Apnea (OSA), but is lesser in severity. It happens more often in women than in men, and these people typically have a normal BMI. The breath is shallower and often times, there may be nasal obstruction. The person may or may not snore.

What is Obstructive Sleep Apnea?

Obstructive Sleep Apnea, or OSA, is when someone stops breathing for 10 seconds or more while sleeping

How is UARS different from Sleep Apnea?

The main differentiation is that the UARS patient has more RERAs (Respiratory Effort Related Arousals) during sleep and the OSA patient just stops breathing. UARS is usually recognized by the person her or himself. They will notice they wake at 2 or 3 am and keep watching the clock wondering if they ever slept at all. In OSA, the person will say they sleep very soundly, “like a rock,” and often it is the person’s partner that notices something is wrong-the person stops breathing. Neither of these groups will feel rested or well upon waking. Both of these groups are typically mouth breathers.

What are the symptoms of UARS?

Not rested in the mornings, wake in the middle of the night finding it difficult to fall back asleep

How is it diagnosed?

A sleep screening that monitors apneic event, hypopnic events, and Respiratory Effort Related Arousal events

How do you treat UARS?

May be a series of treatment. First, the patient must be sure they breathe through their nose well. Then, we must be sure they don’t breathe through their mouth. Once these are confirmed, based on the severity, either a Mandibular Advancement Device (MAD) will be recommended or CPAP.
