Laboratory description

The Akershus university hospital (Ahus) sleep research laboratory is organized under the director of the surgical division. The laboratory holds two Nox Medical A1 devices allocated for in-hospital scientific sleep registrations. Nox T3 polygraphs may be borrowed from the otorhinoloaryngology clinical sleep laboratory located at the same site.

Relevant research projects

  • NordForsk (2019-2022). “Novel wearable sensors and machine learning solutions for personalized diagnostics and treatment of sleep apnoea (NordSleep)”. Norway PI Harald Hrubos-Strøm, consortium project between Iceland, Finland and Norway. Norwegian grant proportion €750.000 (Project total costs: ca. €2.5 M, Dr. Töyräs is the Consortium Head).
  • Hrubos-Strøm is the current project leader of the Norwegian part of the Nord Sleep project. The project is based on two cohorts:

-The Akershus Sleep Apnea (ASAP) epidemiological cohort: 535 community-dwelling participants

initially examined between 2006-2008. A second clinical examination is currently being conducted.

The main research aim of the follow-up project is to investigate relations between co-morbid OSA,

insomnia, and sub-clinical myocardial damage. An electronical sleep diary with an automatically feedback function has been developed in the project. The PhD candidate responsible for data collection

is the post doc applicant of the current study.

-The ASAP clinical cohort: Based on the “Akershus Sleep Apnea Diagnostics and Treatment Evaluation study” with baseline examination of 275 subjects (submitted for publication). A follow-up study approved by the regional ethical committee will examine the feasibility of novel technology based on electroencephalography (EEG) biofeedback and the electronical sleep diary developed in the project.

  • The CAPABLE project, led by AHUS, is an innovation project with participants from healthcare, patient organisations, research groups, industry, and standards organisations. The aim of the CAPABLE project is to develop a platform to enable people to use personal clinical information to manage disease and promote health on an everyday basis.
