In this resource, we look at how the ACIST CVi® Contrast Delivery System optimizes contrast supply. Managing contrast supply can help decrease both dose and waste of contrast, while also reducing the risk of post-procedure CI-AKI for patients presenting for coronary angiography procedures. Some of the key CVi® features and methods that can help reduce contrast media usage are adjusting parameters, real-time dose tracking, optimizing the hand controller, using a smaller catheter, and cine diagnosing.
