AbstractSupplemental oxygen is an essential medication in critical care. The optimal oxygen dose delivery system remains unclear, however. The "dose" and "delivery" of oxygen carry significant importance for resource-limited settings, such as low- and middle-income countries (LMICs). Regrettably, LMICS often experience significant inequities in oxygen supply and demand, with major impacts on preventable mortality. These inequities have become particularly prominent during the global COVID-19 pandemic, highlighting the need for additional investment and research into the best methods to utilize supplemental oxygen and ensure stable access to medical oxygen.Copyright © 2022 Elsevier Inc.
