RESEARCH sub | Respiheart

Background

  • The RespiHeart method origins from mid 2000’s and a wide range of photoplethysmographic studies led by Associate Professor Lars-Göran Lindberg at the Department of Biomedical Engineering, Linköping University, Sweden.

  • The discovery of blood flow signal advantages of measuring in bone tissue, due to more rigid blood vessels, was key to continuous research. Studies focused on the sternum bone confirmed the central heart activity signal and, even more important, identified a high-quality respiration signal. The RespiHeart method was founded.

  • 2010 – 2015, different sensor prototypes were tested in order to define the most appropriate geometrical sensor design as well as effective light sources and detectors. The use of two different light wavelengths enabled the addition of oxygen saturation measurement, without using pulsations.​

Recent studies​

  • Verification of method and technical system was conducted at the Department of Emergency Medicine, at Linköping University Hospital in 2016 – 2017

  • Specific oxygen saturation studies were conducted at Karolinska institutet, Stockholm

       The Swedish Armed Forces Diving and Naval Medicine ​Centre, Karlskrona

  • Homecare studies  – COPD patient self-monitoring​

Ongoing research projects​

  • Respiration monitoring – method comparisons​

  • Extended oxygen saturation studies

  • Explorative blood pressure measurement studies​

  • Development of new respiration measures
