|
|
| Improving the Quality of Life for HD patients |
- WS Far Infrared Therapy Unit can help relieve hematoma and pain caused by venopunctures
- It helps improve access blood flow that enhance dialysis efficiency
- With long term continuous use, it can improve the patency and survival of vascular access (AV Fistula or AV Graft)
- Reduced vascular access complication related surgery and hospitalization
- Reduced medical cost spent on vascular access intervention, surgery, or hospitalization
- WS Far Infrared Therapy Unit is much more user-friendly and safe compared to traditional thermal therapy methods (such as heating pads or warming lamps)

Far Infrared Therapy A Novel Treatment to Improve Access Blood Flow and Unassisted Patency of Arteriovenous Fistula in Hemodialysis Patients
- Adapted from Journal of American Society of Nephrology , pages 985-992 of March 2007 issue.
(Author: Dr. CC Lin et al.)
For one year, patients in the FIR group received FIR Therapy 3 times a week during their dialysis session for 40 minutes, and the FIR emitter was set 25 cm above the surface of AVF during use. Most importantly, No adverse effects was reported throughout the study.
|
As it is shown in the figure, when compared with the patients in the control group who did not receive FIR therapy, the Unassisted Patency of AV fistula was significantly higher in the patients in the FIR group than that in the Control group.
Unassisted Patency of AV Fistula |
FIR group: |
85.9% |
(55 of 64) |
Control group: |
67.6% |
(46 of 68) |
(P<0.01, with significant statistic difference) |
 |
| Conclusion |
- Far Infrared Therapy may effectively increase the incremental change of Access Blood Flow both in single HD session and with long term use (one year)
- Far Infrared Therapy is a convenient, non-invasive treatment that may significantly improve the Access Blood Flow and Unassisted Patency of AV Fistula in HD Patients

AVF under Chronic Vascular Endothelial Inflammation
AVF under Far Infrared Therpay Care  |
- By inducing the expression of Heme Oxygenase-1, Far Infrared Therapy effectively reduces monocyte adhesions in the endothelium cells and therefore reduces the inflammatory responses that cause further endothelial injury and dysfunction. The anti-inflammatory effect of FIR Therapy may provide an answer to how it enhances the survival of AVFs in HD patients

| FAQ |
| 1. |
Q: |
How long will it take to improve the venous pressure and blood flow after receiving FIR therapy? |
A: |
According to the study by Lin et al., FIR therapy can improve venous pressure and blood flow in more than 60% patients during the first HD session when it is administered with setting the emitter 25 to 30 cm above the skin surface of AV fistula for 40 minutes. If HD patients receive the above therapy thrice a week, improvement of venous pressure and blood flow will be observed in about 80% of them after one year and unassisted patency of AV fistula will be increased from 86.1% to 97% at 3 months, from 80% to 91.3% at 6 months, and from 67.6% to 85.9% at one year when compared with the controls. if the patency of AV fistula w95% of patients will not need a further operation in 6 months. Improvement of the venous pressure may vary, while for a normal patient, increasing blood flow can be noticed by a stethoscope after a single treatment. |

Q: |
Will the FIR therapy received during hemodialysis treatment overheat the metallic puncture needles placed in vascular access? |
A: |
According to the physical characteristics of FIR, it is absorbed much more by organism than by needles. In addition, the power density of FIR therapy is relatively low (<30mW/cm2). There is no reported side effect by overheated needles during the study by Lin et al. |
|
| |
| 3. |
Q: |
Can FIR therapy improve the function of synthetic AV grafts? |
A: |
There is no report that FIR therapy will improve the function of AV grafts. According to the unpublished data of Lin et al., however, more than 70% patients will have improvement of access blood flow and dialysis venous pressure after treatment for a few weeks. |
|
| |
| 4. |
Q: |
Will FIR therapy lead to difficulty in hemostasis after hemodialysis? |
A: |
Although there is no evidence that FIR therapy will interfere with the coagulation pathways, we still suggest that patients should complete their FIR therapy at least 30 minutes before the end of every hemodialysis treatment. |
|
| |
| 5. |
Q: |
Can I still continue FIR therapy when there is formation of hematoma? |
A: |
FIR therapy can enhance the absorption of any chronic hematoma; nevertheless, we still won’t suggest its use in the acute phase of hematoma (i.e. with a risk of active bleeding or formation of hematoma within 24 hours) since it will also increase the access blood flow. Treatment can be started again since 24 hours after the formation of acute hematoma or there is no risk of active bleeding. |

Q: |
How is the popularity of FIR therapy in its application to medical care in Taiwan? |
A: |
 Since 1990, we have been conducting research and have successfully applied FIR in various fields of medical care. Our product of good quality, WS FIR Therapy Unit (which benefits more than ten thousand patients), is now available in 84% of hemodialysis centers in Taiwan.
