Chronic lung diseases, like asthma, impose critical challenges on both the patients and the physicians due to the complexity of the diseases. Not only are these diseases tough to accurately assess, many of the diseases can be impacted by other physical and sociological factors. Perhaps a greater difficulty lies in measuring the effectiveness and compliance of the medications including inhaled medications. The invention discovered at the University of California, Irvine, is an “all-in-one,” portable device that offers complete assessment of lung health. It also incorporates a novel technology for monitoring the effectiveness and compliance of a medication, thereby, providing a personalized treatment and care plan for adults and children with asthma.
