Correlation Between Access Blood Flow and Extracorporeal Blood Flow
Correlation Between Access Blood Flow and Extracorporeal Blood Flow

The purpose of this study is to determine if Effective Extracorporeal Blood Flow(eEBF) has correlation with Access Blood Flow (Qa), when eEBF adjusts with Dynamic Arterial Line Pressure (DALP) in patients with Arteriovenous fistulae in hemodialysis treatment.

Accesses that show a large (>15%) decrement over time in vascular access blood flow are associated with a high risk of thrombosis. Serial measurements of vascular access blood flow predict access thrombosis. At the moment, the measurement of access flow is time consuming, operator dependent, so that it cannot be done with every treatment. We hypothesized that extracorporeal blood flow at pressure of -200 to -260 mmHg in arterial line has correlation with access blood flow and this can be used to estimate access blood flow.

Non-Probability Sample

Patients with Chronic Kidney Dissease K-DIGO 5d in hemodialysis.

Arteriovenous Fistula
Other: Dynamic Arterial line Pressure (DALP)
eEBF will be record with dynamic arterial line pressure of -60 mmHg (eEBF-60 mmHg), -100 mmHg (eEBF-100 mmHg), -160 mmHg (eEBF-160 mmHg), -200 mmHg (eEBF-200 mmHg) and -260 mmHg (eEBF-260 mmHg) during the first one half hour of the dialysis session. Access Blood flow will be performed with blood thermal monitor.
