                                            Piper Francis, 17, has been playing softball with lifelong friends since second grade, but last year, she noticed she was having difficulty breathing during practice. She saw multiple doctors who prescribed her asthma inhalers that didn’t help. Then, in early 2025, she was referred to the Exercise Respiratory Center at Cook Children’s – Prosper where her care team identified her breathing issue and helped her recover. Now, she’s back on the softball field and excited to play in her senior year.
John Robertson, M.D., pediatric pulmonologist at Cook Children's Medical Center - Prosper, was Piper’s advocate, quickly figuring out what she needed to improve her breathing and help her continue playing softball. “Almost every day last year, I would feel tightness in my chest and throat. It felt like something was blocking my airway,” Piper said. “I’d show up at softball practice and have to sit out through half of it. Now I’ve been able to go back to practice after seeing Dr. Robertson. He immediately recognized my problem and I felt better in less than a month!”
Piper was diagnosed with EILO and dysfunctional breathing with testing at Cook Children’s Exercise Respiratory Center, which opened in 2023. The Exercise Respiratory Center diagnoses, treats and researches the causes of exercise-induced respiratory symptoms for older children, adolescents and young adults. Some of the many duties of the researchers at the Exercise Respiratory Center, Rebecca Brovina, MSHS, BSN, RN, CPN, and Andy Kreutzer, PhD, CSCS, LSSWB, include gathering data and presenting findings to share with other medical professionals about the diagnosis and treatment of exercise-induced respiratory symptoms.
It’s one of three centers in the U.S. that test continuous laryngoscopy during exercise (CLE) for children and the only center in Texas. During this test, Dr. Robertson will view a patient’s voice box and vocal cords with a scope while the child is exercising.
