Air emboli may occur:
- During preparation of the dialysis catheter, if the dialysis catheter is not clamped when the end cap is removed, air may enter into the patients circulations
- If dialysis needles/access are dislodged air may enter the circulation
- Via the dialysis circuit, when the dialysis circuit lines and catheter or needle connections are not secured adequately, or the dialysis circuit is not primed thoroughly, air may enter the patient's circulation
- Once in "dialysis mode" should air enter the blood circuit, this will be detected and stopped from entering the patient via the venous air detector. However if air enters via the arterial line of dialysis blood circuit before the blood pump, it is possible for this air through gravity, to flow back to the patient be lying/sat lower than the blood pump
