This guide is educational information about lung and respiratory health — it is not medical advice, diagnosis, or treatment, and it is not a substitute for care from a qualified doctor. It does not diagnose, treat, cure, or prevent any condition. See a doctor for diagnosis, an asthma or COPD action plan, and treatment, and do not start or stop any medication without medical advice. Seek emergency help for severe difficulty breathing, gasping, blue or grey lips or face, chest pain, or an asthma attack that doesn't ease with a reliever inhaler — call 911 immediately.
