administered to the patient.
To maintain system accuracy, the user
should ensure that only 100% contrast is injected back to the source.
Contrast Accounting Accuracy Tips:
•
Ensure system is
Paused
if contrast is not being injected to patient.
•
Ensure system is
Active
(unpaused) when contrast is being injected to
patient.
•
Ensure the minimum dwell time (1/2 second) is achieved between
aspirations of contrast and saline.
