Abstract
The presence of asymptomatic hypoxemia (AH) in patients with coronavirus disease (COVID-19) is well described.[1] AH is thought to be responsible for the phenomenon of rapid clinical deterioration and mortality in the hospital setting,[2] and is frequently associated with the delayed escalation of care.[3] In addition, at-home mortality is thought to be elevated among those with AH who are discharged from the emergency department following an apparently low-acuity ambulatory evaluation.[4],[5] Such patients may have profound hypoxemia without significant dyspnea, with the initial sign of deterioration being confined to escalating oxygen requirement.[5]
