ABSTRACT

Coronavirus disease 2019 (COVID-19) is the cause of the pandemic that has affected millions of people worldwide with pulmonary manifestations ranging from mild pneumonia to ARDS and characterized by hypoxia. This has led to questions regarding the most efficacious and least harmful oxygen delivery strategies that minimize exposure to health care workers. In this case series, we present the hospital course of 4 patients that were managed with a multi-component oxygen delivery method in a COVID-19 step down unit.
