Sherri Katz

Senior Scientist, CHEO Research Institute

Dr. Sherri Katz is the Division Chief of Pediatric Respirology at the Children’s Hospital of Eastern Ontario. She is an Associate Professor of Medicine at the University of Ottawa and holds a cross-appointment at the School of Epidemiology, Public Health and Preventative Medicine. She is also a Senior Scientist at the Children’s Hospital of Eastern Ontario. Her clinical research focuses on the use of assistive respiratory technologies for children with chronic diseases, particularly neuromuscular disease and obesity. She has undertaken multicentre cohort studies evaluating cardiometabolic, neurocognitive and quality of life outcomes of positive airway pressure therapy in children with obesity. She has recently led and completed a nine-centre Canadian randomized controlled therapy of lung volume recruitment exercises in boys with Duchenne Muscular Dystrophy. Her research also evaluates predictors and novel diagnostic modalities for pediatric sleep-disordered breathing, pediatric home mechanical ventilation and long-term outcomes of chronic lung disease.

Dr. Katz’s research pursuits are informed by her clinical practice, which includes pediatric sleep medicine, complex respiratory care and home mechanical ventilation. She also holds leadership roles on national and international committees related to Pediatric Respirology and Home Mechanical Ventilation including the Home Mechanical Ventilation and Neuromuscular Disease Network Steering Committee of the American College of Chest Physicians.

  1. Quick, effective screening tasks identify children with medical conditions or disabilities needing physical literacy support.


  2. Sleep quality, physical activity, screen time, and substance use in children with obesity: associations with obstructive sleep apnea


    In children with obesity, more substance-use behaviors were independently associated with greater OSA severity. As there are complex, bidirectional relationships between lifestyle behaviors and OSA severity, interventions need to be comprehensive and multifactorial to ensure successful treatment of OSA and its sequelae in children.

  3. Predictors of postoperative respiratory complications in children undergoing adenotonsillectomy


    Prediction modeling concurrently evaluating comorbidities and polysomnography metrics identified cardiac disease, airway anomaly, and young age as independent predictors of PRAEs. These findings suggest that medical comorbidity and age are more important factors in predicting PRAEs than PSG metrics in a medically complex population.

  4. Target oxygen saturation and development of pulmonary hypertension and increased pulmonary vascular resistance in preterm infants


    Higher targeted oxygen saturation was associated with reduced risk of PH or elevated PVR in extremely preterm infants compared to lower oxygen saturation target.

  5. Sensitivity, specificity, and reliability of the Get Active Questionnaire for identifying children with medically necessary special considerations for physical activity


    The sensitivity, specificity, and reliability of the Get Active Questionnaire (GAQ) for identifying children needing special considerations during physical activity was evaluated among parents of 207 children aged 3 to 14 years
