NASAL CPAP - Continuous Positive Airway Pressure
CPAP is the most common and most effective treatment for OSA. While a person with OSA sleeps, the tissues in the back of the throat collapse and block the flow of air. CPAP therapy introduces controlled pressure (usually through the nasal passages) to hold the soft tissue of the uvula, soft palate, and soft pharyngeal tissue of the upper airway in position, in order to keep the airway open.
A CPAP unit is essentially a microprocessor-controlled blower that delivers pressurized air through a mask that is placed over the nose. When used properly as prescribed by your sleep physician, CPAP will stabilize oxygen levels, breathing patterns and blood pressure.
The amount of pressure required to treat your OSA is generally determined by a titration study in the sleep lab.
CPAP users often report immediate benefits from the therapy. Generally, the more severe the symptoms associated with your OSA, the more dramatic the improvement. Immediate benefits may include cessation of snoring and thrashing around in bed resulting in improved sleep for you and your bedmate.
Continued CPAP use usually results in improved quality of life, including increased energy levels, improved mood, and renewed interest in work and hobbies. Long-term therapy has also been shown to reduce the risk of high blood pressure, stroke and heart failure.http://www.respironicsremstar.com
MASK (interface):
Probably the most important variable in the application of nasal CPAP therapy is the mask or nasal interface through which the CPAP therapy contacts the client's airway. Considerations for a proper fit include:
- Tolerance
- Comfort
- Ability to effect a proper seal with little pressure
- Cost (in some cases)
- Materials (sensitivities)
- Anatomical structure of the face

The high airflow through the nasal passages has a drying effect on the nasal and pharyngeal mucosa. Generally a humidifier is added to increase the humidity level of the air delivered by the CPAP unit.
Humidifiers are available for use with most CPAP units, and are designed to fit the unit and prevent an overly cumbersome package.
Humidifiers can be cold, passover or heated.
