Asthma is a widespread chronic pulmonary disease. Poor management
of Asthma results in over 450,000 hospitalizations each year, the majority
of which are preventable by strict adherence to asthma control medication.
In this thesis, we propose, design and benchmark SmartInhaler, a system
which performs automated and unobtrusive measurement of inhaler usage
behavior and tracking of outdoor air quality parameters.
SmartInhaler consists of an attachment to Metered Dose Inhalers (MDI)
developed as a con gurable platform with an aim to measure patient ad-
herence to asthma control medication. The attachment is designed to
track the parameters associated with asthma medication dosage: number
of dosages, time stamp of dosage, location of use and verify the patient
taking the medication. Furthermore, based on the location of use, Smart-
Inhaler can also track outdoor air quality parameters (concentration of
pollutants) using readily available online pollution data. Tracking air
quality is useful for the asthma patients since their lung airways can be
sensitive to air pollutants.
The SmartInhaler attachment communicates with smart phones or
tablets through a custom Android application developed for delay-tolerant
data collection for both adherence and air quality. In this thesis, we also
demonstrate a proof of concept training module for correcting MDI dosage
administration technique through air-flow modeling.
