Overview
There are three types of sleep apnea: obstructive, central and mixed. Of the three, obstructive sleep apnea (OSA) is the most common. Individuals of untreated sleep apnea stop breathing repeatedly during the night usually for a minute or longer, during their sleep. Most of the time, these individuals are unaware of these episodes because they don't trigger an awakening. Obstructive sleep apnea results from the narrowing or total blockage of the airway. However, in central sleep apnea, there is failure of the central nervous system to send appropriate signals to the muscles of respiration which control breathing. It is also possible for an individual to have a combination of these two types, referred to as mixed apnea.
Classification
Sleep apnea can be classified into three categories:
Obstructive Sleep Apnea (OSA)
- The most common of the three forms
- It results from the narrowing or total blockage of the respiratory airway which occurs when the soft tissue at the back of the throat collapses during sleep
Central Sleep Apnea
- The brain is unable to send appropriate signals to the muscles that control breathing due to the instability of the respiratory center
Mixed Apnea and Complex Sleep Apnea
- Some individuals may have a combination of both types of sleep apnea
- Complex sleep apnea (CompSA), also called 'treatment-emergent central sleep apnea' ), is the emergence central apneas during the use of continuous positive airway pressure (CPAP) or bilevel positive airway pressure (BiPAP) treatment
