Pulse oximeter analysis of peripheral cyanosis distal to an AV fistula.


Arteriovenous (AV) fistulas are routinely constructed for hemodialysis in patients with renal failure. The case of a hemodialysis patient with cyanosis of the hand distal to an AV fistula is described. Pulse oximeter analysis found a saturation of 72% in the cyanotic hand with a normal saturation of 97% in the opposing hand. Evaluation of 11 additional… (More)
