Diagnose Obstructive Sleep Apnea Syndrome
Individuals suspected of having OSAS can consult a sleep apnea specialist at our Centre for clinical assessment.
In order to confirm the diagnosis, polysomnography (multi-channels overnight sleep study) has to be performed. Polysomnography is a painless and non-invasive procedure to record the sleep pattern, heart rate, breathing pattern, muscle activities, snoring and blood oxygen level during sleep. The procedure is conducted in our Sleep Laboratory.
In difficult and complicated cases, such as failure after previous sleep surgery, sleep endoscopy will be carried out under sedation to assess the level of the narrowed segment in the upper airway using a flexible endoscope.
A suitable treatment regimen will be formulated by our experienced specialists in Sleep Apnea for individual patients. Therapeutic options include:
Continuous Positive Airway Pressure (CPAP) devices: To splint the upper airway with air pressure in order to prevent its collapse during sleep.
Oral appliances: To move the lower jaw forward with a custom made dental device, thereby enlarging the upper respiratory tract.
Surgery (mostly for children): To resect or reposition throat structures obstructing the upper airway so as to restore normal flow of air in and out of the lungs.
Modification of lifestyles such as weight control.
Follow-up assessment will be provided at our Centre after treatment to evaluate the patient’s condition to determine whether further support is necessary.
Paediatric Sleep Apnea
Snoring is common in children. Researchers found 10-12% of normal children snore regularly. Most children who snore are otherwise healthy. About 1.5% of children with persistent snoring suffers from Sleep Apnea. If your child snores regularly, he/she may suffer from Sleep Apnea. You should seek the advice of a sleep specialist.
Childhood Sleep Apnea is a chronic illness. Early in the disease, the child snores regularly during the night. He or she may look completely normal during the day. Childhood Sleep Apnea is different from adult Sleep Apnea. In particular, children with Sleep Apnea often do not have daytime sleepiness.
Children with Sleep Apnea suffer from poor sleep quality and intermittent low blood oxygen level during sleep. In more serious cases, they may suffer from problems at school, behavioural problems, delayed growth, or even heart failure. Some of these symptoms are similar to those described in children with attention deficit hyperactivity disorder (ADHD). In fact, some children with Sleep Apnea are misdiagnosed as having attention deficit hyperactivity disorder (ADHD).
How do we diagnose Sleep Apnea in children?
Overnight sleep test is the most reliable way to diagnose Sleep Apnea in children. Sleep test can be done in children of all ages. Your child needs to stay in the hospital for a night. Before bedtime, sleep test technician will put on several measuring wires and belts on your child. These will record brain wave, breathing, heart rhythm, blood oxygen level, etc. The process of sleep test is not painful and will not pose any danger to your child. The sleep test data will be carefully interpreted by specialist, to determine whether your child suffers from Sleep Apnea, and to determine the severity of the Sleep Apnea.
