Table 4 Visual clotting scores.
From: Micro-computed tomography for the quantification of blocked fibers in hemodialyzers
Clotting score dialyzer | Number of dialyzers (%) | |
|---|---|---|
1 | Clean filter | 4 (20) |
2 | Few dark red fibers | 7 (35) |
3 | <50% dark red fibers | 5 (25) |
4 | >50% dark red fibers | 4 (20) |
Venous chamber scoring | ||
1 | no detectable clotting | 7 (35) |
2 | minimal clot formation | 9 (45) |
3 | clots up to 5 cm but dialysis still possible | 4 (20) |
4 | complete occlusion of the air trap | 0 (0) |
