1. Fluid imbalance: Different dialysis machines have different filtrate compositions and dialysis flow regulation, so if you switch to another dialysis machine in the middle of a dialysis session, it can lead to changes in the concentration of various substances in the dialysis fluid, causing an imbalance in the electrolyte and acid-base balance in the body fluids.
2. Blood coagulation: There may be subtle differences in the blood pathways and filters on the dialysis machine, and changing the dialysis machine may result in an increased risk of blood coagulation in the new pathways and filters.
3. Mechanical failure: Dialysis machines are complex medical devices, and replacing a dialysis machine may involve the risk of mishandling or mechanical failure, such as blood pump malfunction and filter leakage.
4. Risk of infection: Dialysis machines and dialysis rooms are potential sources of infection, and when replacing a dialysis machine, new bacteria or viruses may be brought in, increasing the risk of infection.
Therefore, when changing to another dialysis machine halfway through dialysis, it is necessary to go through a rigorous process to ensure that the new dialysis machine and access are clean and intact, and that accurate monitoring and adjustments are made to minimize potential harm. It is best to consult with specialized doctors and nurses and to closely monitor body reactions during the dialysis process to deal with any abnormalities in a timely manner.
