  • Silent hypoxia: A harbinger of clinical deterioration in patients with COVID-19. [Case Reports]
    Am J Emerg Med. 2020 May 22 [Online ahead of print]Wilkerson RG, Adler JD, … Brown R
  • Patients infected with the SARS-CoV-2 virus can present with a wide variety of symptoms including being entirely asymptomatic. Despite having no or minimal symptoms, some patients may have markedly reduced pulse oximetry readings. This has been referred to as "silent" or "apathetic" hypoxia (Ottestad et al., 2020 [1]). We present a case of a 72-year-old male with COVID-19 syndrome who presented t…
