Two years ago, Mary Ann Stansberry responded to an ad that popped up on her Facebook page asking for people to participate in an asthma study. A start-up company called Propeller Health was running the program, and it sent her silicon chips in sleeves to slip over her inhalers, and apps to put on her phone and laptop
The goal of the study was to track how often Stansberry and nearly 1,200 other residents of Louisville experienced respiratory distress, by tracking their puffs and correlating them with levels of pollution. Studying asthma in Louisville made sense. It sits within a bowl of low hills around the Ohio River and has a notorious reputation for sooty air, Saharan heat islands and pollen-clogged skies that make it the fourth-worst city in the country for springtime allergies and asthma.
