How Is Obstructive Sleep Apnoea (OSA) Diagnosed?

The following examinations may be conducted to diagnose OSA:

  • Physical examination. The doctor may do a physical exam and inquire about your symptoms and medical history. They may also conduct flexible nasendoscopy (study of your throat and nose using a small lighted tube with a camera at the tip) to evaluate the potential sites of narrowing in the upper airway.

  • Polysomnography (PSG). Polysomnography is a lab sleep examination that measures oxygen levels and brain waves to determine the causes of sleep disruption.

  • Home sleep study (HST). This is a self-performed study that is used to diagnose sleep apnoea.

What Is Snoring & Obstructive Sleep Apnoea (OSA)

Snoring is the rattling or snorting noises a person makes during breathing while sleeping.

Obstructive sleep apnoea is associated with interruptions in breathing during sleep, causing the body to receive less oxygen and waking up frequently at night. Obstructive sleep apnoea is caused by an obstruction of the airways, leading to snoring, restlessness and gasping for air during sleep.
