While access flow remains fairly constant during a hemodialysis treatment, cardiac output decreases an average of 20% during the treatment causing less blood flow to be available to sustain the body’s vital functions. A healthy body will respond to this by increasing peripheral resistance to sustain the blood supply to the heart and brain. Other considerations include: - The site of a vascular access affects average flow values. Upper arm sites typically have higher flows than lower arm sites. - Patients with initial high flow fistulas are at greater risk for cardiovascular problems. A fistula may over-mature and present a flow over 2 L/min. - Autologous fistulas tend to remain sufficiently patent to sustain dialysis at lower flows than do prosthetic grafts. - A straight upper arm prosthetic graft may initially exhibit an overly high flow. Graft flow tends to decrease over time, so banding a prosthetic graft is not advised. Access flow and cardiac function of these patients should be monitored monthly to ensure that access flow drops before cardiac complications arise. 1 Tucker T et al, "Central Hemodynamic Profiling (CHP) during Outpatient Hemodialysis (HD)," J Am Soc [![Download the Hemodialysis Handbook](https://no-cache.hubspot.com/cta/default/40716/cc66c597-0270-4391-b210-11cdf17dd005.png)](https://cta-redirect.hubspot.com/cta/redirect/40716/cc66c597-0270-4391-b210-11cdf17dd005) - [** ](https://www.facebook.com/sharer/sharer.php?u=https://blog.transonic.com/hemodialysis/proactive-cardiac-function-monitoring-during-hemodialysis&title=Proactive%20Cardiac%20Function%20Monitoring%20during%20Hemodialysis&picture=http://cdn2.hubspot.net/hubfs/40716/Central_Hemodynamic_Profiling.png&description=Considerations%20for%20proactive%20measurement%20of%20cardiac%20function%20during%20hemodialysis.) - [**](http://www.linkedin.com/shareArticle?mini=true&url=https://blog.transonic.com/hemodialysis/proactive-cardiac-function-monitoring-during-hemodialysis&title=Proactive%20Cardiac%20Function%20Monitoring%20during%20Hemodialysis&summary=Considerations%20for%20proactive%20measurement%20of%20cardiac%20function%20during%20hemodialysis.) - [**](https://twitter.com/share?source=https://blog.transonic.com/hemodialysis/proactive-cardiac-function-monitoring-during-hemodialysis&text=Proactive%20Cardiac%20Function%20Monitoring%20during%20Hemodialysis%20-%20https://blog.transonic.com/hemodialysis/proactive-cardiac-function-monitoring-during-hemodialysis) - [**](mailto:?subjetc=&body=Proactive+Cardiac+Function+Monitoring+during+Hemodialysis%20-%20https://blog.transonic.com/hemodialysis/proactive-cardiac-function-monitoring-during-hemodialysis) [![Transonic_logo-456](https://blog.transonic.com/hs-fs/hubfs/email-assets/newsletter/Transonic_logo-456.png?width=190&height=50&name=Transonic_logo-456.png "Transonic_logo-456")](https://www.transonic.com/) © 2023 Transonic.
