In the hemodialysis process, coupled with the pressure of the blood pump, improper handling during the operation, can cause air embolism.

Complication of hemodialysis pipeline coagulation: dialysis pipe coagulation often starting at cava filter, due to various reasons in the blood blocking filter fiber precipitation pores, so that the blood gradually solidified, which can be extended to the whole dialysis pipe.
