Why can patients with similar OSA severity respond differently to treatment?
One contributing factor is a low arousal threshold: a tendency to awaken easily in response to breathing disturbances during sleep.
These repeated arousals can interrupt sleep before the upper-airway muscles have an opportunity to restore stable breathing. That makes arousal threshold an important part of understanding the physiology behind OSA.
For dentists and physicians working together, the takeaway is practical: consider more than anatomy when evaluating treatment response. Oral appliance selection, titration, and follow-up should reflect the individual patient.
