Pulse oximetry and respiratory monitoring during a sleep assessment — sleep study

If your doctor suspects sleep apnoea, they may recommend a sleep study. The idea of being monitored overnight can feel strange, but the test is painless and gives important information.

Quick answer: sleep study

  • A sleep study records breathing, oxygen levels, heart rate and sleep overnight.
  • Full polysomnography is done in a sleep lab; selected patients may have a home test.
  • It is painless — sensors are placed on the skin.
  • Results guide whether treatment such as CPAP is needed.
