Obstructive Sleep Apnoea (OSA) in Children  

Recent research shows that the ratio of Children suffering from OSA is much higher than what is begin generally perceived.  Children having enlarged tonsils and/or adenoids, allergic rhinitis, or obesity are much more prone to OSA.  Children with OSA may experience symptoms including:

  • Snoring
  • Periods of shallow breathing during sleeping
  • Mouth breathing
  • Bed wetting
  • Excessive daytime sleepiness
  • Difficulty in paying attention or impaired cognitive function

If left untreated, OSA in children can cause poor growth, impaired neurocognitive development, and even high blood pressure. Therefore, it is important to carry out early evaluation. If your child has been experiencing snoring and sleep problems, please consult your paediatrician for early evaluation and treatment

Sleep Study

A sleep study (also called Polysomnography) is required to confirm the diagnosis of OSA in children, by detecting various sleep activities including brain function, breathing patterns, chest and abdominal muscle movements. Sleep study is usually conducted overnight in a sleep lab. The child will first put on pyjama, and the sleep technician will place some signal detectors onto the body of the child. When the child falls asleep, the signal detectors will collect relevant sleep activity data and transmit them to the computer for analysis. The progress will be performed overnight until around 7 a.m. on the next day.   Sleep specialist doctor will then base on the apnoea-hypopnea index (AHI) to confirm the diagnosis of OSA.
