Which peak flow meter color indicates emergency treatment if symptoms do not improve with rescue meds?

• A. Green
• B. Yellow
• C. Red
• D. Blue

Answer: (C)

Red signaling is used to indicate an emergency when symptoms do not improve after using rescue medication. A peak flow meter helps track airway obstruction by comparing the current expiratory flow to a person’s best, and the color zones guide actions: green means asthma is well controlled, yellow indicates caution and the need to potentially step up treatment or seek evaluation, and red shows that airflow is severely reduced and urgent care is needed. When symptoms stay bad after using a fast-acting inhaler, it’s an emergency to seek medical help promptly, and use the rescue inhaler as directed while reaching care. Blue isn’t a standard peak flow color in typical action plans.
