CPAP therapy provides slight air pressure to keep your airway open. It is the most common and effective treatment for OSA.

  • Apnea: Apnea is a period of cessation of airflow for at least 10 seconds, there are several types of apnea associated with sleep:
    • Central Sleep Apnea: this occurs when the body stops breathing during sleep, typically because of problems with the brain or heart. This is different from obstructive sleep apnea because it does not involve a blockage of the airway.
    • Complex Sleep Apnea: a condition in which the patient is diagnosed with obstructive sleep apnea and CPAP treatment causes central sleep apnea.
    • Obstructive Sleep Apnea: a stoppage of breathing during sleep due to an obstructed airway, mainly caused by relaxation of the tongue and throat during sleep which collapses to close the path to the lungs. These stoppages endure until the body rouses itself sufficiently to re-open the airway.

 

  • CPAP: Continuous Positive Airway Pressure; this treatment uses a machine, hose, and mask to send a continuous flow of air into your nose as you sleep to create a level of air pressure that keeps your airway open. CPAP is an effective treatment for most patients’ obstructive sleep apnea. Patients using CPAP often report feeling much better and having more energy.

 

  • Hypopnea: unlike apnea, which is a complete stoppage of airflow, hypopnea is not a blockage, but reduction of more than 50 percent of airflow, usually associated with a reduction in blood oxygen levels.

 

  • Apnea-Hypopnea Index (AHI): average number of apnea or hypopnea per hour of sleep.

 

  • Polysomnography: the process of monitoring several body systems (including breathing, heart rate, and brain activity) during sleep; this is typically done in an overnight sleep study.
