Sleep Apnoea
Welcome
Sleep apnoea is a highly prevalent sleep disorder affecting approximately 3-7% of men and 2-5% of women, with a higher prevalence among middle-aged and elderly individuals.
Sleep apnoea is a serious public health problem, and is associated with numerous adverse health consequences, including
- hypertension
- cardiovascular disease
- metabolic disorders
- cognitive impairment.
Types of Sleep Apnoea
There are three types of sleep apnoea:
- Obstructive sleep apnoea (OSA)
- Central sleep apnoea (CSA)
- Complex sleep apnoea syndrome (CompSAS)
OSA, the most common form, is characterised by recurrent episodes of partial or complete upper airway obstruction during sleep, leading to intermittent hypoxia and sleep fragmentation.
CSA is less common and is defined by the absence of respiratory effort due to a failure of the central nervous system to initiate breathing.
CompSAS involves the presence of both OSA and CSA.
