In peak flow monitoring, which range defines the green zone?

Green zone reflects good asthma control: peak flow at about 80-100% of the patient’s personal best with no symptoms and stable condition. This range shows the airways are functioning normally and there’s no immediate need to change treatment. The other descriptions align with caution or danger: 50-79% with increased rescue inhaler use fits the yellow zone, signaling the need to adjust therapy; less than 50% or severe symptoms is the red zone, indicating a medical emergency; 60-90% with mild symptoms partially overlaps with yellow because symptoms or higher rescue inhaler use imply not being in optimal control. Therefore, the 80-100% range with no symptoms best represents the green zone.
