What are the best techniques to reduce POCUS artifact and increase the diagnostic accuracy of lung ultrasound?   

It is important to first clarify that essentially all of lung ultrasound IS artifact, and this is a great illustration of how artifact can actually help us to make a diagnosis rather than obscuring it. When we see B-lines, for example, that is an artifact that does not represent a similarly appearin...

Well, this is an interestingly worded question. Some of the major findings of lung ultrasound (A-lines and B-lines) are actually artifacts themselves, so if you're looking for these, you don't want to decrease artifact. Lung mode on many modern machines actually turns artifact filtering off ...
