Application of MSP430 and DSP C5000 in mobile patient and environmental monitoring

Asthma is a widespread chronic respiratory disease with rising prevalence. Current state-of-the-art in practice of long-term asthma management at best comes down to usage of smartphone-based asthma-diary for manual entry of subjectively perceived symptoms, and provision of medication reminders and alerts on environmental asthma-triggers. Nevertheless, by interfacing smartphone to low power, minimally obtrusive sensors, collecting information on the condition of the patient and the environment may enhance quality of treatment. In this paper we give an overview of the ongoing development of proof-of-concept of such system utilizing two sensors, based on MSP430 and TMS320C5505 DSP. First is the respiratory sounds monitoring sensor, utilizing detection of asthmatic wheezing, a common symptom related to severity of asthma. The second sensor is the mobile air quality sensor measuring pollutant gas concentrations and meteorological conditions, used for identification of potential asthmatic triggers in the patients surroundings.
