What Is Sleep Apnea?

Sleep apnea is a breathing-related sleep disorder characterized by repeated disruptions in normal breathing that can last from a few seconds to over a minute. In most cases, the pauses in breathing are due to an obstruction of the airway. The blocked airway may result in a loud snort or gasp, wake the patient up, and disrupt sleep. Depending on the length and frequency of an episode, an individual may experience substantial oxygen deprivation. Sleep apnea may significantly impact the quality and quantity of one’s sleep.

Types Of Sleep Apnea

Types of sleep apnea include:

Obstructive Sleep Apnea (OSA)

Obstructive sleep apnea occurs when a patient experiences a partial or complete blockage of the airway during sleep. This is the most common type of sleep apnea. The severity of OSA is based on the number of breathing events per hour of sleep and may be:

  • Mild OSA – 5-15 episodes per hour of sleep
  • Moderate OSA  – 15-30 episodes per hour of sleep
  • Severe OSA – 30+ episodes per hour of sleep

Central Sleep Apnea (CSA)

Central sleep apnea occurs when the brain fails to signal the body to breathe during sleep. This condition is less common than OSA.

Mixed Sleep Apnea (MSA)

Mixed sleep apnea is a combination of both obstructive sleep apnea and central sleep apnea.

What Is Upper Airway Resistance Syndrome (UARS)?

It is commonly believed that sleep apnea begins as subtle airway collapse which may or may not be associated with snoring. This may have a harmful effect on an individual’s health and sleep quality because of chronically disrupted sleep. Upper airway resistance syndrome is a precursor to obstructive sleep apnea, and it is important to identify and treat patients with UARS since they have a higher risk of developing obstructive sleep apnea in the future.

Symptoms Of Sleep Apnea & Upper Airway Resistance Syndrome

Symptoms of sleep apnea and UARS vary from patient to patient. These symptoms include:

  • Loud snoring
  • Choking or gasping during sleep
