The document discusses using a video game-based peak flow meter to help younger asthma sufferers track their lung capacity and medication effectiveness. It proposes designing a portable, interactive peak flow meter in the form of a video game cartridge that children can use to gamify taking peak flow readings multiple times per day. The game would calculate peak flow values from inhaled air and transfer the data to be stored. This design aims to make peak flow monitoring less stigmatic and more engaging for children ages 3 to 7.
