Sleep Report


Each 'Level 2' sleep study performed by us includes a comprehensive, 3-page sleep study report that is sent to the referring doctor. The sleep study report routinely includes the following:

  • Patient details, summary of relevant measurements, sleep-related complains and medical history
  • Sleep-related diagnoses, including colour print-out from patient sleep-study data; where appropriate, abnormal brain wave activity, abnormal respiratory events and abnormal leg movements are outlined)
  • Personalised treatment recommendations based on polysomnogram findings and detailed patient history; our recommendations are based on up-to-date treatment guidelines and evidence based medicine
  • Detailed sleep-statistics, calculated after the polysomnogram has been fully analysed by experienced Sleep Study Scorers
  • Detailed respiratory statistics, snoring volumes and oxygen saturation profile

Sleep Study Scoring

All our sleep studies are individually analysed by experienced Sleep Study Scorers. Our senior staff are registered sleep technologists with the BRPT (Board of Registered Polysomnographic Technologists), an internationally recognised qualification in sleep technology. Studies are analysed according to international standards outlined by the AASM (American Academy of Sleep Medicine), ASA (Australian Sleep Association) and ASTA (Australian Sleep Technologists Association).
