The Ectosense has been developed by a Belgian company as a device to measure the number of breathing stops (AHI’s) in Sleep dyspnoea. The ectosense is a very comfortable and practical device to wear and is a cheap and high qualitative alternative for sleep analysis in specialised centers. By using the ectosense diagnosis of sleep dysnoea can be improved and provide earlier re-integration to work. Yellow Factory supports the implementation of the device in the Netherlands.
