Different levels of the nomenclature. The nomenclature levels are presented in order from Level 1 to Level 4. Abbreviations may be used according to each center’s praxis from Level 1 or more detailed. Levels may be combined according to the user’s preference, e.g., Levels 2 and 4. The drainage cannula is placed on the left of the hyphen (“-”). The return cannula is placed on the right side. More precise positions (that do not directly relate to a cannula or catheter) are given as indexes, e.g., femoral (f), left (l) or right (r), atrium (a). For the complete lists of abbreviations, see Table 2 and Additional file 1
