Oxygen Delivery Devices in Hypoxemic Respiratory Failure

Abstract Oxygen therapy by appropriate oxygen delivery device (ODD) at different stages is an essential part of hypoxemic respiratory failure management. The choice of ODDs depends on the degree of hypoxemia, precision of delivery, patient comfort, risk of transmission of infection to Health Care Worker (HCW), and the cost. Management of hypoxemic respiratory failure depends on underlying etiology and pathophysiology of the disease process. Study from the current global pandemic of novel coronavirus disease 2019 (COVID-19) showed that the severity of hypoxemia is independently associated with in-hospital mortality and can be an important predictor risk of admission to intensive care unit. In this review, we will discuss the different ODDs, their indication for use along with the advantages and disadvantages.
