What Is AV Access?
AV access, short for arteriovenous access, is a surgically created connection that allows healthcare providers to access the bloodstream for hemodialysis. It is essential for individuals with end-stage kidney disease who require regular dialysis treatments to remove waste products and excess fluid from the blood.
The most common types of AV access are AV fistulas and AV grafts.
Why AV Access Matters
A well-functioning AV access provides reliable blood flow for effective dialysis treatments while helping reduce complications such as infections and blood clots.
Types of AV Access
- Arteriovenous (AV) fistula
- Arteriovenous (AV) graft
- Central venous dialysis catheter (temporary access)
Benefits of Healthy AV Access
- Reliable blood flow during dialysis
- Improved dialysis effectiveness
- Lower risk of complications with AV fistulas
- Long-term vascular access for treatment
How Is AV Access Monitored?
Healthcare providers regularly examine AV access by checking blood flow, listening for a bruit, feeling for a thrill, and using ultrasound or other imaging tests if problems are suspected.
How Home Care Can Help
Home care professionals monitor the access site, educate individuals about proper care, encourage daily checks for a thrill, reinforce infection prevention measures, and report any concerns to the healthcare team.
Home Care Tip
Protect your AV access by avoiding tight clothing, heavy lifting, and blood pressure measurements on the affected arm whenever possible.
Frequently Asked Questions About AV Access
What is the best type of AV access?
An AV fistula is generally considered the preferred option because it typically lasts longer and has a lower risk of infection than other access types.
How often should I check my AV access?
You should check your access daily for the vibration, or thrill, and notify your healthcare provider if it changes or disappears.
Can home care help with AV access?
Yes. Home care professionals provide education, monitor the access site, and help identify problems early to support successful dialysis treatment.
When to Contact Your Healthcare Provider
Contact your healthcare provider immediately if you notice redness, swelling, drainage, bleeding, severe pain, or if the thrill or bruit is absent or noticeably weaker.
