Oxybag is an application I created that is designed to assist those who use portable oxygen tanks. The app connects to a backpack that holds the portable oxygen tank (designed by a group member). Oxybag App warns the user when their heart rate is too fast, when they’re walking too fast as well as when the oxygen concentration around them is too low. This app also can connect to the users doctor, who can more easily review a patient’s health with a helpful graph. Oxybag app is designed to further assist those who use portable oxygen tanks.
