Upper extremity arteriovenous fistula does not affect pulse oximetry readings

Abstract

An upper extremity AVF alters blood pressure and temperature measurements when compared with the contralateral non-AVF side, but there is no difference in SpO2 provided an adequate signal quality is detected.

Range for Normal Body Temperature in Hemodialysis Patients and Its Comparison with That of Healthy Individuals

“…Additionally, the long-term survival and quality of life of patients on hemodialysis is dependent on an appropriately placed vascular access; the most reliable long-term method of achieving this being the construction of an arteriovenous fistula (AVF) [15,16]. The resultant arterialization of the vein alters the blood flow distal to the AVF and can theoretically change the skin and axillary temperature [17]. …”

Digital pressure and oxygen saturation measurements in the diagnosis of chronic hemodialysis access-induced distal ischemia

“…In comparison, a previous study reported a significant reduction of distal arterial pressure after the creation of an AVF; however, no significant change was observed in O 2 Sat. 26 Also, we found a difference in O 2 Sat of the two sides in the case group (92.9% 6 2.1% vs 95.6% 6 1.4 %; P ¼ .001). Halevy et al 20 described five patients with steal syndrome, in whom O 2 Sat increased from a median of 50% (range, 42%-63%) to 98% (range, 80%-100%) by therapeutic intervention.…”
