  • Apnea: Apnea is a period where airflow stops for at least 10 seconds; there are several types of sleep apnea:
    • Central Sleep Apnea: when the body stops breathing during sleep, typically because of problems with the brain or heart. It does not involve a blockage of the airway so it is different from obstructive sleep apnea.
    • Complex Sleep Apnea: the patient is diagnosed with obstructive sleep apnea and central sleep apnea is caused by the CPAP treatment.
    • Obstructive Sleep Apnea: due to an obstructed airway, a stoppage of breathing occurs, 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 airway is re-opened when the body wakes itself sufficiently.
  • CPAP: Continuous Positive Airway Pressure; this treatment uses a hose, machine, and mask to create a level of air pressure that keeps your airway open through a continuous flow of air into your nose as you sleep. For most patients, obstructive sleep apnea CPAP is an effective treatment. Patients using CPAP often report having more energy and feeling better.
  • Hypopnea: hypopnea is not a blockage, but a reduction of more than 50 percent of airflow, usually associated with a reduction in blood oxygen levels. This is unlike apnea, which is a complete stoppage of airflow.
  • Apnea-Hypopnea Index (AHI): average number of hypopnea or  apnea per hour of sleep.
  • Polysomnography: typically done in an overnight sleep study, polysomnography is  the process of monitoring several body systems (including heart rate,  breathing, and brain activity) during sleep.
