Potential Benefits of HighVolumeHDF
Compared to Conventional HDb
The opportunity for patients to feel better and live longer1a
HDF is an advanced dialysis treatment and one of the fastest growing dialysis therapies around the world. When high volume is achieved in the HDF treatment, it can help you:
a. Based on reduced mortality risk and slower decline in quality of life in patients treated with HVHDF compared to standard HD.
b. The clinical studies showing the above potential outcomes with HVHDF were conducted outside of the United States and did not involve the 5008X CAREsystem. Patient experiences may vary when being treated with HVHDF therapy.
c. Not all studies show the same outcome and not all patients will experience the same benefit.
d. HDF patients in this study were younger and had fewer comorbidities.
What Is the 5008X CAREsystem?
Fresenius Medical Care is proud to introduce the 5008X CAREsystem, the first in-center dialysis device designed to perform HVHDF for patients in the United States. The 5008X CAREsystem allows your care team to provide advanced dialysis therapy.
- First device in the United States that can do both conventional HD and HDF
- Smart alarm technology to reduce noise
- Intelligent technology customizing treatment to your individual needs

I used to feel weak and wobbly after in-center hemodialysis—sometimes I’d lose my balance. Since switching to HDF with the 5008X CAREsystem, I’m steadier on my feet and recover faster after treatment.
Alexander
Patient
I felt a difference very soon after starting the hemodiafiltration (HDF) therapy. I achieved HighVolumeHDF in three weeks. I felt lighter and my energy came back quickly after treatment. I was coaching baseball again, leading outreach at church, and spending time with my kids without needing hours of rest. I even returned to fishing, working out, and doing things around the house. HighVolumeHDF helped me regain strength and independence.
Ronald
Patient
Before HighVolumeHDF, Ronnie used to be exhausted, frustrated, and sometimes I had to leave work to pick him up from the clinic because he couldn’t drive home. Since starting the new therapy, everything has changed. His recovery is quicker, his mood is better, and he is himself again. HighVolumeHDF has brought stability, energy, and peace back into our home.

Indications for Use:
Machine:
The 5008X™ system is indicated for intermittent hemodialysis treatment for patients with acute and chronic renal failure in a healthcare facility. Therapy options for patients weighing more than 40 kg include: Hemodiafiltration (HDF), Hemodialysis (HD), Hemofiltration (HF) and Isolated Ultrafiltration.
The 5008X Machine is equipped with a bibag® system, but it may also be used with liquid bicarbonate using the connector included with the machine. The bibag system is indicated for use in patients undergoing extracorporeal bicarbonate hemodialysis for acute and chronic renal failure. The bibag system is intended to be used as one component in the preparation of dialysate according to a physician’s prescription in a 3-stream proportioning hemodialysis machine equipped with the bibag module.
The 5008X Machine is available equipped with a Crit-Line Clip (CLiC) Monitor System. The optional CLiC system is used to non-invasively measure hematocrit, oxygen saturation and percent change in blood volume in real time for application in the treatment of dialysis patients with the intended purpose of providing a more effective treatment for both the dialysis patient and the dialysis technician. Based on the data that the monitor provides, the clinician/nurse, under physician direction, intervenes (i.e. increases or decreases the rate at which fluid is removed from the blood) in order to remove the maximum amount of fluid from the dialysis patient without the patient experiencing the common symptoms of dialysis which include nausea, cramping and vomiting.
Caution: Federal (US) law restricts these devices to sale by or on the order of a physician.
