Propeller Health and the Robert Wood Johnson Foundation, through their Air Louisville program, are using sensors on asthma inhalers to track when, where and how often inhalers are used. This helps patients manage symptoms, and city officials warn of increased chances of asthma severity in certain areas.
Sensors attach to inhaled medication, and a smartphone app and physician-facing website analyze the data. Patients are given the inhalers for free. The use of “rescue medication” (short-acting bronchodilators) and daily maintenance medication are monitored.
Air sampling monitors are overlayed onto the EPA monitor backbone to determine connections between air quality, environmental factors, and asthma severity.
Propeller Health plans to expand its asthma monitoring program to five U.S. cities.
