ECMO: extracorporeal membrane oxygenation; ICU: intensive care unit; CRP: C-reactive protein.
* If dexamethasone is unavailable, other glucocorticoids at equivalent doses are reasonable alternatives.
¶ For those who are stably on minimal supplemental oxygen (eg, 1 to 2 L/min), it is reasonable to forgo dexamethasone and use remdesivir alone, particularly in patients who are immunocompromised and within 10 days of illness onset.
Δ The clinical benefit of remdesivir is uncertain in patients who need support beyond low-flow oxygen, but it is reasonable to use it in those on high-flow or noninvasive ventilation, particularly if they are immunocompromised and receiving immunomodulatory agents for COVID-19.
◊ Tocilizumab and baricitinib should be used with caution in immunocompromised patients, among whom the safety of further immune modulation with such agents is uncertain.
