Pre-test and post-test probability for diagnosis (ping @Aidan_Baron) used:
B-lines are an unusual lung ultrasound finding outside of heart failure and dialysis with acute dyspnoea.
Which leaves acute pneumonitis.
If they have #CORVID19 symptoms and B-lines diagnosis highly likely

B-line numbers correlate with pathology severity in all diagnoses. More B-lines≊worse disease.
Can be used for severity assessment (triage) & afterwards response to therapies.
#CORVID19 also displays sub-pleural consolidation—easy to spot (ping @icmteaching @Wilkinsonjonny).

Pleural lines should be sharp and clear, ideally with A-lines showing good aeration. As lung disease occurs this will broaden (≠ pleural thickening from say asbestos, that looks different) and become thick and lumpy.
This is normal—

Whereas this is not normal.
Note also how the broadened line also creates B-lines that eradicate the horizontal A-line.

These findings should reverse as the patient gets better.

However, deterioration, and we're talking ventilated patients here, that merits proning, will likely show postero-basal de-aeration ± effusions of varying size.
Left to right: lung (!), spleen, kidney.

Getting all this information, keeping your #POCUS machine clean and not contaminating unaffected patients or yourself is going to be hard.
I am particularly concerned about proning. This needs to be rehearsed as we have so little need of it in my unit.

IMHO emergency department and acute medics should upskill in lung #POCUS now—I've always thought that of course
People with a @FUSICuk and @FAMUSultrasound qualification may find themselves teaching, with very good material, for the wrong reasons, a lot!

Keep safe. We need you!
