The Propeller system defines your level of asthma control by how often you are using your reliever medication. We use national guidelines (USA-based National Heart, Lung and Blood Institute, or NHLBI) to determine this level of control. If your asthma is not well or is poorly controlled, we recommend talking to your doctor about ways to improve your health. We also use the Asthma Control Test (ACT) to learn more about how your level of asthma control changes over time.
