The Four Types of Sleep Apnea

  • Obstructive sleep apnea - The most common form of this disorder, obstructive sleep apnea (OSA) occurs when a patient's throat closes as the individual inhales during sleep and the patient cannot suck air into their lungs. Since muscles relax during sleep, the soft tissue of the pharynx relaxes and expands, obstructing air flow in the upper respiratory tract. This obstruction reduces the amount of oxygen in the blood and forces the patient to wake up and take a deep breath. Men from age 30 to 50 are the main group affected by OSA. Often, people will experience mild OSA at some point in time in their lives; however, chronic or severe OSA requires medical attention.
  • Central sleep apnea - Central sleep apnea, or Cheyne-Stokes respiration, is a relatively rare form of sleep apnea that occurs when the region of the brain responsible for controlling the breathing muscles temporarily fails. Central sleep apnea differs from OSA in that the patient's pauses in breathing are due to a lack of effort to breathe.
  • Mixed apnea - Mixed apnea is a combination of OSA and central sleep apnea. Chronic OSA can sometimes cause central sleep apnea. Although the exact cause is still unknown, weight-related, cardiovascular, and respiratory conditions can contribute to mixed sleep apnea.
  • Complex sleep apnea - Complex sleep apnea is a form of mixed sleep apnea. With this unusual condition, a patient still experiences sleep apnea even when the physical obstruction to breathing is removed.
