Lung ultrasound is increasingly being used in a critical care setting to assess the severity of COVID-19, and to assess response to prone ventilation.
Modern ultrasound machines use numerous techniques to minimise the presence of ultrasound artefacts. Lung ultrasound however often relies on the user recognising typical artefacts and patterns caused by ultrasound and air interactions at the pleural surface.
A “lung” preset should turn off the various smoothing and artefact minimisation algorithms routinely used. Turn compound imaging and harmonic imaging off and reduce dynamic range. This is particularly important if want to characterise and quantify B-lines – both these rely on artefact creation.
