CPAP and BiPAP 
This is the most common treatment for OSA and consists of either continuous or bi-level positive pressure (CPAP/ BiPAP), which is delivered via face or nasal mask to stent the upper airway passage open while asleep.  If used as instructed, this therapy is very effective. Some patients have trouble using this therapy due to mask related discomfort.

Oral appliance
For patients with mild or moderate OSA, an oral appliance can be an effective therapy option. This custom-made appliance stabilizes the lower jaw in a more forward position, which moves the tongue and the attached soft tissue out of the way so that patients can breathe better at night.

Adjunct therapy
​Other treatment alternatives in the management of OSA include weight loss, positional therapy with special pillows and body positional devices, which can sometimes lead to significant improvement of OSA. Other lifestyle changes that should be implemented include smoking cessation, alcohol avoidance, and sleep hygiene.  Correction of nasal obstruction (e.g. decongesting sprays, breath-rite strips, nasal surgery) can sometimes help with CPAP compliance. 

An oral device moves lower jaw and tongue forward to prevent collapse.

Positional device keeps patients on the side to diminish throat collapse
