Respiratory System Diseases Diagnosis & Care
At Chicago Pulmonary Specialists, we use state-of-the-art technology to diagnose and treat all forms of respiratory disorders. Our facilities include:
- A private pediatric pulmonary practice (our main practice)
- A Cystic Fibrosis Center (the Cystic Fibrosis Center of Chicago)
- A not-for-profit organization (the Cystic Fibrosis Institute)
- A human performance laboratory (the Sports Physiology Center of Chicago)
Dr. Steven R. Boas and his team are specially trained to address the following conditions:
- Asthma, including allergic and non-allergic asthma and exercise-induced asthma
- Sports Performance Disorders, including exercise-related shortness of breath, vocal cord dysfunction, inducible laryngeal obstruction, impaired exercise ability, and exercise fatigue
- Vocal Cord Dysfunction
- Exercise-Related Breathing Disorders
In addition, our practice provides comprehensive treatment for a wide variety of respiratory issues, including:

Inflammation of the airways can cause them to narrow and secrete thick mucus, or phlegm, which can clog the small airways, thereby resulting in a cough, wheezing (a high-pitched whistling sound made while you breathe), and shortness of breath.
A cough may also produce sputum (phlegm with saliva), which is coughed up from the lungs. Wheezing and coughing may be symptoms of asthma, bronchitis, bronchiolitis, emphysema, pneumonia, or another respiratory tract infection.
Cystic fibrosis (CF) is a progressive, genetic disease that causes persistent lung infections and limits one’s ability to breathe over time.
In people with CF, a defective gene causes a thick, sticky buildup of mucus in the lungs, pancreas, and other organs.
These disorders include, but are not limited to, recurrent and chronic pneumonia, chronic bronchitis, immune deficiencies, and chest wall deformities such as pectus excavatum (in which the breastbone sinks into the chest), pectus carinatum (a protrusion of the sternum and ribs), and rib abnormalities – all of which can make breathing difficult.
