Digit-compression, or digit-pressure, is a diagnostic maneuver that your doctor uses in the case of redness of the skin to evaluate whether or not he or she has disappeared.
It is to press on the erythematous part with a finger and observe the skin color variation.
More objective is the vitro-pressure method, which allows you to visualize the possible disappearance of the redness during pressure, through a glass or transparent material pressed on the skin. Bibliografiamodifica wikitesto
