About Us

Riley Hospital for Children

As one of the country's top children's hospitals, Riley Hospital for Children at IU Health strives to provide the most advanced care and premier pediatric research in the nation.

We provide comprehensive children's care in every field of pediatric medicine and surgery and are ranked as the tenth best Pediatric Pulmonology department in the country by USNews & World Report.

Riley Hospital for Children’s physicians are recognized across a number of different specialty areas, bringing care to children across Indiana and the Midwest with the most innovative treatments and the latest technology. We are continually pioneering new programs and treatment options in an effort to best serve our patients.

Specialized Care for Breathing Problems

Our Pediatric Pulmonologists provide thorough evaluation then design a treatment and follow-up program to meet the needs of each child. The kinds of problems treated include asthma, wheezing, coughing, chest pain, viral respiratory infections, structural abnormalities in the respiratory system, and chronic lung disease in premature infants.

Riley Hospital for Children Sleep Disorders Center at Indiana University Health offers state-of-the-art evaluation of sleep disorders of all kinds. It is the only such center in Indiana and is nationally recognized.

The Latest Technologies for Diagnosis

Riley Pulmonology at IU Health Diagnostic Center provides specialized lung function testing for children through the Pediatric Pulmonary Function Laboratory. This specialized laboratory performs testing for physicians throughout Indiana and offers fiber-optic bronchoscopy. Our metabolic and exercise testing laboratory, which is also available to physicians throughout Indiana, is used to help evaluate the cause of a child's breathing problems.

Riley Hospital also has a Center for Pediatric Lung Function, which occupies approximately 500 square feet of dedicated space on the second floor of the Riley Hospital for Children’s Outpatient Center.  Specialized equipment within this laboratory includes the Carefusion Infant PFT system, which measures the raised volume forced expiratory flows, partial flow-volume curves (VmaxFRC), and lung volumes via plethysmography, tidal volume, compliance and resistance.  The Ecomedics nitrogen washout equipment in this laboratory is the newest model and measures lung clearance index, along with measuring nitric oxide using single and multiple breath tests, and nasal nitric oxide in cooperative and non-cooperative patients. Other equipment includes Koko spirometers used to measure preschool spirometry and the Vivometrics system use to assess inductance plethysmography in infants.

Our Cystic Fibrosis Center

The Riley Hospital for Children Cystic Fibrosis Center at Indiana University Health has been serving families in Indiana and Midwest states for over 30 years. Riley Cystic Fibrosis Center at IU Health is the only center accredited by the Cystic Fibrosis Foundation in the state of Indiana and one of the largest in the country.

Riley Cystic Fibrosis Center at IU Health works closely with the clinics at St. Joseph Regional Medical Center in South Bend, Lutheran Hospital in Ft. Wayne, Deaconess Hospital in Evansville, and the Adult Cystic Fibrosis Center at Indiana University Hospital in Indianapolis.
