OBSTRUCTIVE SLEEP APNEA-CENTRAL SLEEP APNEA-MIXED APNEA
In central sleep apnoea, which is more difficult to treat, the airway isn't blocked. Instead, your brain periodically fails to trigger your body's normal breathing reflex, resulting in breathing stoppages. (CPAP or BiPAP are the only treatments for this type of condition)
Some people may have mixed apnea — a combination of obstructive sleep apnoea and central sleep apnea.
In all these types, breathing is interrupted, usually between 10 and 30 seconds at a time, until you rouse to a lighter level of sleep or brief wakefulness. Breathing resumes, but after you again fall asleep, the cycle continues.
Sleep apnoea is most common after middle age — and particularly among those who are overweight — but it can also affect children. Many people may be unaware of their condition.
