Can you do blood pressures on old arm fistula?

It is generally not recommended to take blood pressure on an arm with a fistula, especially if it is an arteriovenous (AV) fistula used for dialysis. This is because the pressure cuff can disrupt the blood flow and potentially damage the fistula. Instead, blood pressure should be measured on the opposite arm or in an alternative site to ensure the integrity of the fistula is maintained. Always consult with a healthcare professional for specific guidance in such cases.
