ABSTRACT
Dyspnea is reported in a minority of patients affected by coronavirus disease 2019 (COVID-19). Even patients with pneumonia can present hypoxemia without any respiratory distress, a phenomenon known as "silent" or "happy hypoxemia". During the current pandemic there were only a few studies conducted on this subject and these were quite heterogeneous. Therefore, the prevalence of "silent hypoxemia" varied substantially. While studies did not show a clear tendency of "silent hypoxemia" to poorer outcomes compared to hypoxemia presenting with dyspnea, several showed that patients with "silent hypoxemia" are not protected from poor outcomes either. There is a need for a uniform definition of "silent hypoxemia", in order to better guide clinicians and investigators. More studies are needed to shed light on the mechanisms of "silent hypoxemia", as well as its presentation and influence in the disease's progression and outcomes, so as to better assist physicians in the care of COVID-19 patients.
