Obstructive Sleep Apnea (OSA) affects more than 10% of the adult population. Diagnosing OSA is done by polysomnography which is a test offered in most larger cities. An overnight study with pulse oximetry is a useful tool to help detect sleep disturbances and determine effectiveness of CPAP/BIPAP treatment.
There are a few ways to treat OSA. The most successful, cost-effective, and widely-accepted method is with flow generators called CPAP machines. The other treatment options are surgery to the upper airway and specialized dental appliances.
CPAP therapy involves the rental or purchase of a flow generator, and the use of an interface for delivery. There are many different types of interfaces on the market that include nasal, oral, or full face masks. The best advice you can get on choosing the correct mask and machine would be to consult with a respiratory therapist or a physician who specializes in sleep medicine.
