Online production of substitution fluid makes HighVolumeHDF easy and efficient
- The preparation of sterile, non-pyrogenic and bicarbonate-buffered substitution fluid for HighVolumeHDF by ONLINEplus technology is based on a double-stage filtration process via DIASAFE®plus dialysis fluid filters and offers:
- No extra costs for an additional single-use filter
- No need for ready-made rinse solutions for priming, bolus or reinfusion with ONLINE fluid in all treatment modes
- Extensive amounts of substitution fluid for HDF available
- No waste bag needed due to rinse port
- The water quality for HighVolumeHDF has to meet the same international standards (ISO 23500-5) as for high-flux HD
- Fresenius Medical Care offers easy and reliable water quality management as part of a complete therapeutic system for HighVolumeHDF – technically advanced, affordable and sustainable

High-volume HDF – The clinical & economic value
High-volume HDF – The clinical & economic value
NICE (The National Institute for Health and Care Excellence) states that in-center HDF should be considered rather than in-center HD1,12,14
As per the NICE guidelines, it is suggested that HDF may have mortality benefits compared to standard HD and is cost-effective.15
HDF versus HD: Cost effectiveness analysis12,14-16
HDF considered as cost effective to HD
Reduced EPO requirements of up to 9 %14 with HDF based on weighted average calculation
Economic benefits for units using Fresenius Medical Care equipment as no switching costs from HD to HDF (including higher convection volumes), which means neutral budget impact
Fewer side effects for HDF compared to high-flux HD14
The NICE committee indicated additional benefit of HDF over high flux HD, the potential reduction in dialysis-related amyloidosis in patients on long term dialysis
Convection volume
The NICE committee did not make any specific recommendation, but agreed that it was likely that patients who achieved higher convection volumes would get a greater benefit from HDF

High-volume HDF - Simple & reliable
ONLINEplus technology – Reducing workload, increasing usage
- An advanced therapy often means more complexity, more handling steps and an increased workload for healthcare professionals. But thanks to sophisticated products and technology from Fresenius Medical Care, the application of HighVolumeHDF in daily clinical routine has been greatly simplified4,18,20
- In addition, unique features such as AutoSub plus automatically improve substitution rates in post-dilution HDF and support the application of HighVolumeHDF4,18
- Our innovative blood lines are developed based on the idea that HighVolumeHDF should be as easy and safe to handle as HD. With a standard setup of a 5008S or 6008 CAREsystem, you can already perform HighVolumeHDF without additional preparations
- As a result, the application of HighVolumeHDF is not more complex or costly* than conventional HD. You can even switch from HD mode to HighVolumeHDF mode with the same equipment and disposables
* Cost should always be considered in the context of relevant local healthcare systems.
Safety features create confidence
In particular during high-volume HDF where high blood flows are aspired for, monitoring of the venous access is essential as blood loss would become critical within a very short time. The 5008 series and 6008 CAREsystem offer a sophisticated safety feature as standard in all machines that has been designed to reduce the risk of external blood loss:
- Venous Access Monitor (VAM) – if an alarm is emitted, the blood pump is stopped immediately, and the venous clamp is closed. This aims to give the nursing staff more time to react appropriately to critical pressure changes
- Blood line kinking and filter clotting monitoring (BLK) - Clotting and Kinking detection - Kinks in the tubing system might result in a mechanically generated hemolysis. The BLK function detects kinked tubing between the blood pump and the venous bubble catcher as well as clots beginning to develop in the dialyzer, and issues a warning.
The innovative and highly automated features support nursing staff by streamlining daily workflows and support high and consistent levels of patient safety. The result is easy integration of high-volume HDF into daily routine.

High-volume HDF dialyzers
Albumin retention capabilities of FX CorAL
Maintenance hemodialysis patients often experience increased protein catabolism, amino acid and albumin loss during dialysis, which contributes to malnutrition.
According to a study by Ehlerding et al., the albumin loss with FX CorAL was less than 1.4 g during a typical HDF treatment of four hours.6
In another study by Melchior et al., FX CorAL was found to have the lowest albumin sieving coefficient decrease over time compared to other seven dialyzers.
Dialyzers investigated in this study: FX CorAL 600 / 80 (Fresenius Medical Care); FX CorDiax 600 / 80 (Fresenius Medical Care); xevontaHi 15 / 20 (B. Braun); Polyflux 140 H /170 H (Baxter); ELISIO™-15H /19H (Nipro); FDX-150GW / 210GW (Nikkiso Medical); THERANOVA 400 (Baxter); SUREFLUX™-15UX /19UX (Nipro).
Effective middle molecules removal
Clinical evidence shows better removal rates of β2-microglobulin and myoglobulin for FX CorAL compared to reference dialyzers during four hour high-voume HDF treatment.6
Fiber geometry to facilitate high subsitution volume
Study subgroup analysis showed an inverse relationship between convection volume and risk of mortality.8,24 According Basile et al., the recommended convection volume is the maximum possible, of at least 23 L. It is proposed that a convection volume of at least 23 L (for 1.73m2 body surface area) is suggested to enhance the clinical outcomes of HDF therapy. 25
Variations on pressure drop within the FX CorAL HDF dialyzers.26,27
- Increased inner diameter of 210 µm compared to 185 µm substantially reduces the pressure drop within the hollow fiber (according to the Hagan-Poiseuille law)26,27
- Lower flow resistance leads to a decrease in pressure drops which is proposed to cause less stress for the blood22
