Sleep apnoea is the reduction or the complete stopping of breathing during sleep. Patients may not be aware of the apnoea but will feel the other symptoms during the wake.
There are many types of sleep apnoea such as:
Obstructive sleep apnoea (OSA): It is the reduction or the stopping of breathing during sleep due to the narrowing or the complete closure of the airways.
Central Sleep apnoea (CSA): When the brain fails partially or completely to send a signal to the chest muscles to move for breathing (usually this type of apnoea is not associated with snoring)
Complex or Mixed apnoea: This is the mixture between OSA and CSA.
