The BLUE-protocol decision tree - performed on dyspneic patients who will be admitted to the ICU

The BLUE-protocol combines signs, associates them with a location, resulting in seven profiles:

 - The A-profile associates anterior lung-sliding with A-lines.

 - The A’-profile is an A-profile with abolished lung-sliding.

 - The B-profile associates anterior lung-sliding with lung-rockets.

 - The B’-profile is a B-profile with abolished lung-sliding.

 - The C-profile indicates anterior lung consolidation, regardless of size and number. A thickened, irregular pleural line is an equivalent.

 - The A/B profile is a half A-profile at one lung, a half B-profile at another.
