If a patient’s peak flow reading is in the yellow zone, what should they do?

When a patient’s peak flow reading is in the yellow zone, it indicates that their asthma is not well controlled and that they may be experiencing increased airway inflammation or narrowing. In this situation, it is crucial for the patient to follow their asthma action plan, which will typically include taking prescribed medications to help alleviate symptoms and improve their lung function.

The yellow zone often signifies the need for additional treatment, such as the use of a rescue inhaler or other prescribed medications to stabilize the patient's condition. Following the asthma action plan ensures that the patient manages their symptoms proactively and prevents potential progression to a more severe state, which might occur if the correct steps are not taken.

Engaging in normal activities without taking action can lead to worsening symptoms. Similarly, stopping the use of all inhalers is inappropriate, as it could contribute to increased respiratory distress. Seeking immediate emergency care is unnecessary at this point unless the patient's condition rapidly deteriorates, which the action plan typically helps to avoid. Therefore, the most appropriate response when in the yellow zone is to adhere to their action plan and take the prescribed medications.
