  1. The severity of SARS-CoV-2 patients is difficult to quickly assess in the ED.

  2. The ABG test is a quick and easy tool that can help identify more severe patients.

  3. CT cannot be used on all suspected SARS-CoV-2 infected patients admitted in ED.

  4. The CT volumetry correlates well with the values of severity reported by the ABG test.
