CPAP vs
Inspire Therapy
If you've struggled to tolerate CPAP, Inspire offers a different path to treating obstructive sleep apnea — no mask, no hose, no machine. Here's how the two treatments actually compare.
Two Approaches to Treating Obstructive Sleep Apnea
CPAP and Inspire are both effective treatments for obstructive sleep apnea — they just work very differently. CPAP keeps your airway open from the outside using pressurized air delivered through a mask. Inspire keeps it open from the inside using gentle nerve stimulation to move your tongue forward while you sleep.
CPAP is the gold-standard first-line therapy for moderate-to-severe sleep apnea. When it's tolerated and used every night, it's the most effective treatment available. The challenge: many patients can't tolerate the mask, hose, or noise — and stop using it within months.
Inspire is FDA-approved specifically for patients who cannot tolerate or do not benefit from CPAP. A small device implanted under the skin of the upper chest stimulates the hypoglossal nerve during sleep, gently moving the tongue and airway muscles forward. You turn it on with a small remote at bedtime — no mask, no hose, no machine. Capital ENT has performed Inspire surgery for over 10 years.
