Sleep apnea is a potentially serious sleep disorder in which breathing repeatedly stops and starts. If you snore loudly and feel tired even after a full night’s sleep, you might have sleep apnea.


The main types of sleep apnea are:

  • Obstructive sleep apnea, the more common form that occurs when throat muscles relax
  • Central sleep apnea, which occurs when your brain doesn’t send proper signals to the muscles that control breathing
  • Complex sleep apnea syndrome, also known as treatment-emergent central sleep apnea, which occurs when someone has both obstructive sleep apnea and central sleep apnea


If you think you might have sleep apnea, see your doctor. Treatment can ease your symptoms and might help prevent heart problems and other complications.


At Entific, we offer different types of sleep apnea tests that provide an accurate diagnosis for patients who think they might have sleep apnea. Available in Hong Kong and Macau, a test assesses breathing throughout just one night. How do sleep apnea tests work? The sleep test Hong Kong uses a sleep test ventilator to record various data and determine if you have sleep apnea. It is simple, risk-free, and painless, tracking your breathing status while you sleep. While one test alone is required, if your physical condition, lifestyle, age, and exercise habits change, you may need to repeat it.


The signs and symptoms of obstructive and central sleep apneas overlap, sometimes making it difficult to determine which type you have. The most common signs and symptoms of obstructive and central sleep apneas include:

  • Loud snoring
  • Episodes in which you stop breathing during sleep — which would be reported by another person
  • Gasping for air during sleep
  • Awakening with a dry mouth
  • Morning headache
  • Difficulty staying asleep (insomnia)
  • Excessive daytime sleepiness (hypersomnia)
  • Difficulty paying attention while awake
  • Irritability


A sleep apnea test requires only 5-8 hours of sleep data to make an accurate diagnosis. In this time, various data including heartbeat and breathing are collected. The test can be done in the hospital or at your home in Hong Kong or Macau, depending on your situation. Read more details on
