Q: What is the Yellow Zone for people with asthma?
Leonard Bacharier, MD: The Yellow Zone is the first indication that your short-term asthma control is worsening.
Patients in the Yellow Zone start to experience asthma symptoms, a drop in peak flow, increased use of their quick-relief albuterol inhaler, and nighttime awakenings.
People with asthma need to be well informed of the signs of worsening asthma. They should be given a written, predetermined strategy – called an Asthma Action Plan – for what to do when asthma is worsening.
Q: What can someone in the Yellow Zone do to prevent falling to the Red Zone?
Dr. Bacharier: The Red Zone is a sign you are experiencing severe asthma symptoms and may require emergency medical care.
Medication strategies to prevent falling to the Red Zone may include:
- Use of quick-relief albuterol inhaler
- Use of inhaled corticosteroids
- Other therapies depending on age, type of disease, severity and background medication use
Q: What are signs that suggest a person with asthma needs to seek medical help?
Dr. Bacharier: Asthma symptoms that clearly affect respiratory function include:
- Persistent cough
- Chest tightness
- Difficulty breathing
In addition to those symptoms, signs that indicate a severe asthma attack include:
- Fingers and lips turning blue
- Inability to speak in complete sentences
Each of these should prompt immediate emergency care.
