Digital Hemodynamics in the Normotensive and Hypertensive States. I. Digital Mean Arterial and Venous Pressures, Blood Flow, and Vascular Resistance.
AJ LTHOUGH the peripheral arterial circulation in hypertension has been well studied in the past, 1-4 to our knowledge the technic of rheoplethysmography5 6 has never been utilized for this purpose. Since this method offers a more accurate and detailed appraisal of the digital circulation than heretofore available, it seemed worth while to utilize it in a reinvestigation of the digital hemo-dyn...
متن کاملDynamic venous access pressure ratio test for hemodialysis access monitoring.
BACKGROUND Early recognition of arteriovenous graft (AVG) dysfunction in hemodialysis (HD) patients followed by prompt corrective procedures reduces AVG thrombosis rates and lengthens access survival. We developed a method to prospectively monitor AVGs that uses an algorithm to calculate venous access pressure (VAP) during HD from the venous drip chamber pressure (VDP). METHODS Sham HD with b...
متن کاملHigh hemodialysis vascular access flow and impaired right ventricular function in chronic hemodialysis patients
There are limited data showing right ventricular preload increase due to high-flow arteriovenous fistulas (AVFs). This cross-sectional study investigated whether high AVF flow had an impact on right ventricular function in patients undergoing hemodialysis. Sixty-four patients aged between 18 and 85 years who were on routine hemodialysis with >2 hemodialysis sessions per week for at least 3 mont...
متن کاملComparing the Effect of Simple Filtration Hemodialysis and Ultrafiltration Hemodialysis on Arterial Oxygen Saturation and Blood Pressure in Chronic Dialysis
Background and purpose: Hypoxemia and hypotension are important complications of hemodialysis in patients with chronic renal failure that are linked to several factors, including the type of filters used. The aim of this study was to compare the effect of simple filtration hemodialysis and ultrafiltration hemodialysis on blood pressure and blood arterial oxygen level. Materials and methods: In...
متن کاملSuccessful Long-Term Central Venous Access; Daily Home Hemodialysis Blood Access.
Successful long-term central venous access is a complex subject. The concept of "long term" implies that continued surveillance will be required. This also requires the catheter to be placed, initially, in its best configuration. To achieve long-term performance and durability, a thorough understanding of all aspects related to the catheter, catheter placement, and catheter maintenance is essen...
