Effectiveness of High Flow Oxygen Therapy in Patients With Hematologic Malignancy Acute Hypoxemic Respiratory Failure

High-flow nasal oxygen \[HFNO\] therapy is a focus of growing attention as an alternative to standard oxygen therapy. By providing warmed and humidified gas, HFNO allows the delivery of higher flow rates \[of up to 60 L/min\] via nasal cannula devices, with fraction of inspired oxygen(FiO2) values of nearly 100%.
