How to select the proper injection rate for an arteriogram

How to select the proper injection rate for an arteriogram?

The easiest way to select the proper rate is to give a test injection of contrast agent by hand to estimate the rate of flow.

The injection rate should approximate the intrinsic rate of flow of the vessel. Giving a test injection is always prudent to ensure that the catheter is in the appropriate location.

Accidental power injection into the subintimal space or a tiny branch vessel may occur if this recommendation is not followed.
