Q. Explain Injection Rate and Volume?

This is best achieved by injecting directly into the ventricular chamber. Midcavitary position of the catheter ensures that there is no ventricular ectopy; sufficient contrast is delivered to chamber and apex, valve function is not interfered with and there is no endocardial staining.

Injection Rate and Volume

A pressure injector or flow injector can be used to deliver contrast material into the ventricle. Most laboratories follow a pressure cut-off of 1000 psi. For the pigtail and most of the other catheters, an injection rate of 10 to16 ml/sec and a volume of 30 to 55 ml is desirable. Care should be taken to avoid air embolism.
