Polysomnography

    • Polysomnography (PSG) is a type of sleep study that uses a multi-parameter monitoring system to aid in the diagnosis of various sleep disorders.
    • The PSG sleep study is performed overnight in a controlled environment such as a hospital ward or a dedicated sleep laboratory.
    • The PSG device that is used monitors many body functions including brain activity, eye movements, muscle activity, heart rhythm, breathing functions,
      blood oxygen levels and body position.
    • Not all medical aids pay for PSGs, you may have to have a Home based sleep study.
    • All options will be discussed with you prior to the procedure being booked.

    Home Based Sleep Studies

    • Home based studies also known as sleep screening, monitor fewer
      parameters and are used more for the diagnosis of sleep related breathing
      disorders.
    • Home based studies are conducted in your own home. You will be required
      to collect and return the sleep equipment. A consultant will show you how
      to connect yourself to the equipment at home.
    • Not all medical aids pay for Home based studies, you may have to be
      admitted to a facility for the sleep test.
    • All options will be discussed with you prior to the procedure being booked.

    CPAP Titrations

    • If you have been diagnosed with having a sleep related breathing disorder,
      you will in all likelihood need to spend a night sleeping on a CPAP therapy
      device.
    • CPAP therapy is the Gold standard for treating Obstructive Sleep Apnea (OSA)
      and is also used to manage other breathing disorders like hypoventilation
      and hypoxemia.
    • The titration test involves sleeping on a small bedside device that is attached
      to a mask via a hose. The device blows a gentle stream of air through the
      mask which is worn over your nose or nose and mouth. This stream of air
      has a splint like effect in the airway preventing airway collapse (obstructive
      apnea). The air pressure will fluctuate according to your specific needs
      through the night.
    • The results of this titration are very important in determining your long term
      treatment on CPAP therapy. Your equipment supplier will request a copy of
      these results in order to advise you on the best device and mask to
      purchase.
