A few simple measures can make a big difference in managing limited medical oxygen supplies to treat severe COVID-19 patients. This is the message from a group of emergency physicians as part of an ad hoc consultation on crisis oxygen management hosted by the
COVID-19 Clinical Research Coalition. The consultation was prompted by the medical oxygen shortage in several countries battling rising numbers of COVID-19 cases.
The
measures recommended by the group to optimize available oxygen include reducing oxygen leaks and wastage, prioritizing low-flow oxygen devices and those that waste the least amount of oxygen, using the lower end of target oxygen saturation ranges, and regular monitoring of patients’ oxygen saturation to ensure oxygen is started and stopped only as needed.
The group emphasizes that these measures are intended for immediate action in crisis situations only, and they also direct clinicians and policymakers to several sources of existing guidance on oxygen supply and management to help rectify the problem over the longer term.
