PICU Admission Rates in Pediatric Cancer and Hematopoietic Stem Cell Transplant Patients Receiving High-flow Nasal Cannula Oxygen Therapy on the General Ward.

The use of high-flow nasal cannula (HFNC) oxygen therapy is growing as an alternative to standard oxygen. However, its use in patients treated for malignancies, including hematopoietic stem cell transplantation (HSCT) patients, is controversial. In this retrospective cohort study, we assessed outcomes of pediatric cancer and HSCT patients (including nonmalignant indications) with acute hypoxemic respiratory failure treated with HFNC on the ward.
