Sleep Apnea is a common sleep disorder which follows loud snoring. Around 4% of male and 2% of female are suffering from this disease, which accounted for 400,000 of population in Hong Kong. Obstructive sleep apnea (OSA) is the most common category of sleep-disordered breathing. The airway of the patient was obstructed during sleep, which leads to air cannot pass through smoothly. An apnea presents for minimum 10 second interval between breaths. Repeatedly experience apnea (serious condition may up to 30 times or above) would disrupt normal sleep. Patients would suffer from low level of blood oxygen content and brain damage. Those affected may experience sleepiness or feel tired during the day, enhance increase risk of having heart attack, diabetes and stroke.

Type of sleep apnea
1.Obstructive Sleep Apnea, OSA
This is the most common type of sleep apnea, which accounted for 90% of sleep-disordered breathing. Human airway is composed of collapsible walls of soft tissue. Excessive soft tissue would narrow the airway, and therefore breathing might be obstructed. OSA may be caused by accumulating of body fat, enlarged tonsils and soft palate. As body muscles ordinarily relax during sleep, or gravity gives rise to a narrowed airway, suffocation may occur. People who are obesity, long neck circumference, elder, short chin may have high risk of OSA.

Normal, unobstructed airway

By controlling the muscles of soft tissue during sleep, the airway would remain unobstructed.

Obstructed airway

As muscles which are used to control soft tissue are loosened, the airway becomes narrowed. Patients might snore and feel difficult to breath.

2.Central Sleep Apnea, CSA
The basic neurological controls for breathing rate malfunction and fail to give the signal to inhale when experienced stroke, trauma.

3.Mixed Sleep Apnea, MSA
Patient was diagnosed with OSA and CSA at the same time.

You could have a try on CPAP or CPAP mask in CPAP trial centre, with specialists’ instruction of on the usage and selection of products.

There are mainly two types of devices to help with sleep apnea, which are CPAP and APAP respectively. The former clears the airway by setting up specific air pressure by doctors. While the latter could automatically detect how the patients breathe. By providing minimum air pressure to clear the airway, patients’ throat would not feel dry easily.
