4-Step Self Fistula Check
Your AV fistula is your lifeline for dialysis.
Checking it daily takes less than one minute – but it can prevent serious complications.
Here is the simple 4-step method Self AV Fistula Examination.
Step 1 – Know Your Fistula
- Identify your usual first needle puncture site (where dialysis typically begins).
- Understand that this is the best point for daily sound monitoring.
- Sit in a quiet place before checking.
You are simply becoming familiar with your own AV access during Self AV Fistula Examination.
Step 2 – Use the Stethoscope Correctly
- Place the earpieces comfortably in your ears.
- Hold the round flat part (diaphragm) gently.
- Place it on the first needle puncture site.
- Do not press too hard.
- Keep it steady — do not move it around.
No technical training required.
Step 3 – Listen for Changes
You are checking only one thing: the sound during Self AV Fistula Examination..
✔ Continuous whooshing sound →
Normal: a Iow-pitched, continuous, soft rumbling sound, like a machine running steadily in the next room. It
carries on between heartbeats.
A steady, uninterrupted sound means your fistula is functioning well.
⚠ Interrupted or weak →
Possible narrowing: the sound climbs. It becomes high-pitched, whistling or squeaky. Sometimes it stops being
continuous and you hear it only with the pulse – what we call the interrupted sound. Rising pitch is the signal.
Inform your dialysis team.
🚨 No sound at all → contact your dialysis unit immediately.
Disclaimer: – In case of very low pulse rate or low blood pressure sound can be weak/interrupted. Don’t panic check your blood pressure and pulse rate. If it is normal then you re check after sometime and if weak/interrupted sound persist contact your nearest AV fistula surgeon.
Contact your AV Fistula Surgeon immediately.
That’s it.
No complicated medical terms.
Just listen daily as part of your Self AV Fistula Examination.
Problems usually develop gradually, and there are often warning signs. But not always. A fistula can clot
suddenly with no warning after a drop in blood pressuw during dialysis, after dehydration, after long
pressure on the needle sites, or after sleeping on the arm. Never assume you will get notice.
They start with narrowing (stenosis).
If detected early:
- Angioplasty can fix it.
- Surgery can be avoided.
- Dialysis continues smoothly.
Early listening saves fistulas.
Note: If a bulge in your fistula bleeds, press firmly and directly on it and get emergency help at once. Do not wait, and do not drive yourself.
Step 4- Act Quickly
Most fistula blockages do not happen suddenly.
They begin with narrowing (stenosis).
If detected early:
- Angioplasty can restore flow
- Surgery can often be avoided
- Dialysis continues smoothly
Early listening saves fistulas.

FAQs
How often should I perform Self AV Fistula Examination?
It is suggested to examine your fistula daily or just before your next dialysis appointment.
Can low blood pressure affect the sounds during Self AV Fistula Examination?
Yes, if your blood pressure is low, it could make your continuous sound like an interrupted sound. When your blood pressure returns to normal, you should recheck your examination.
What should I do if there is no sound?
If you do not hear anything when examining your AV Fistula/ graft, it likely means you have a blood clot. You should contact your doctor as soon as possible.
Can mild stenosis be detected by Self AV Fistula Examination?
Self-examinations can usually detect severe levels of stenosis, while mild to moderate levels of stenosis generally produce a continuous sound.
Is special training required for Self AV Fistula Examination?
Yes, it is important for patients to receive the necessary training to enable them to correctly detect variations and make appropriate decisions based on that information. The AVF Care Workshop provides patients with practical experience and training in this area.
