Sažetak
Asthma is one of the widespread chronic diseases. Rising prevalence increases the burden of personal disease management, financial expenditures and workload, both on sides of patients and healthcare systems. Firstly, the medical background of asthma is given. Pathology and symptoms are presented. Afterwards, the problem of persistent asthma management is introduced with a short overview of traditional disease management techniques. A review on approaches to asthma telemonitoring is made. Effectiveness of home peakflowmetry is analysed. Employment of low power wireless sensor networks (WSN) paired with smartphone technologies is reviewed as a novel asthma management tool. Using the technology, the aim is to retain the disease in a controlled state with minimal effort, invasiveness and cost, and assess patient’s condition objectively. WSN-s for sensing of both asthma triggers in the environment, and continuous monitoring of physiological functions, in particular respiratory function are reviewed. Sensing modalities for acquiring respiratory function are presented. Signal acquisition prerequisites and signal processing of respiratory sounds are reviewed. Focus is put on low-power continuous wheeze detection techniques. At the end, research challenges for further studies are identified.
