Obstructive Apnea:
Central Apnea:
Hypopnea:
"Apnea-hypopnea index, or AHI, is an index used to assess the severity of sleep apnea based on the total number of complete cessations (apnea) and partial obstructions (hypopnea) of breathing occurring per hour of sleep. These pauses in breathing must last for 10 seconds and are associated with a decrease in oxygenation of the blood. In general, the AHI can be used to classify the severity of disease (mild 5-15, moderate 15-30, and severe greater than 30)."
"Obstructive sleep apnea is a potentially serious sleep disorder in which breathing repeatedly stops and starts during sleep. Several types of sleep apnea exist, but the most common type is obstructive sleepapnea, which occurs when your throat muscles intermittently relax and block your airway during sleep."
"Central sleep apnea is a disorder in which your breathing repeatedly stops and starts during sleep. Central sleep apnea occurs because your brain doesn't send proper signals to the muscles that control your breathing."
"Hypopnea is a medical term for a disorder which involves episodes of overly shallow breathing or an abnormally low respiratory rate. Hypopnea is considered by some to be less severe than apnea"
"CPAP, or Continuous Positive Pirway Pressure, is a treatment that uses mild air pressure to keep the airways open. CPAP typically is used by people who have breathing problems, such as sleep apnea."
