Low-FLux and High-Flux
- According to the hydrophobic properties, high flux dialyzers absorb toxins associated with uremia and reduce cytokines and complement activators, thus, diminish inflammatory responses. It may also retard the long-term complications of hemodialysis.
- The ‘low-flux’ cellulosic dialysers could easily remove the smaller toxins such as urea and creatinine, but larger molecules that are normally removed by normal kidneys were unable to fit through the pores.
- Made of cellulose membranes with a higher permeability compared to low flux dialyzers, high flux dialyser allows much faster removal of fluid. In haemodiafiltration, rapid removal (and replacement) of fluid is essential so high-flux dialysers are always used for this type of treatment.
- Compatible with multiple sterilization methods including steam, ethylene oxide and gamma radiation;
- Capable of high levels of toxic clearance;
- Higher mechanical strength which results in lower albumin loss and allows for faster and easier processing of molecules.
It is highly recommended that a hemodialysis facility is equipped with sufficient specialized and support staff, such as nephrologists, dialysis doctors and dialysis nurses.
To start performing hemodialysis, start the blood pump and adjust the blood flow with the ‘+’ and ‘-’ buttons on the monitor. Then, deactivate the Bypass. When deactivated, the Bypass button will no longer be highlighted green, and this will prompt the start of dialysis.
Then bring up the treatment parameters with the Overview icon, and if or when necessary, minimize ultrafiltration with the MIN-UF icon. To start the bolus press the Bolus icon. Refer to the instructions on the screen and confirm. Then check the height of the venous blood level.
When the time for the end of treatment arrives, an acoustic signal will chime and the machine will go to Bypass. As soon as this happens, touch the Terminate therapy icon. If done correctly, the Reinfusion window will open automatically.
Continue by carefully connecting the patient’s arterial line to the saline bag, and meticulously emptying the bicarbonate cartridge during reinfusion.
When the venous red sensor detects sufficient saline, the blood pump stops automatically. Carefully disconnect the venous line from the patient. Finally empty the dialyzer, follow the instructions and confirm.
- All hemodialysis machine areas, consultants and nurses’ rooms should be air-conditioned, and treatment areas should have temperatures of 70 to 72F with 55 t0 60% humidity;
- Stable supply of electricity is required, this is why the voltage supply should be stable and uninterrupted during hemodialysis procedure;
- Each dialysis machine should be equipped with oxygen and vacuum outlets.
