5.2 Pressure Limiting
The purpose of the programmed pressure limit is to protect the patient, the catheter, and any
disposable device attached to the injector.
As a general rule, set pressure limit no higher than the max pressure rating of the weakest component
in the fluid path (tubing, stopcocks, connectors, catheters, administration sets, etc.).
Max pressure rating examples for an example scenario:
• Tubing - 1200 psi
• Stopcock - 1050 psi
• Catheter - 1200 psi
In this case, set the pressure limit no higher than 1050 psi because anything higher could potentially
cause the component to fail.
Typical factors to consider and how they affect Pressure:
Consider the above factors when setting pressure limit to achieve the desired injection flow rate.
Proper pressure limit setting optimizes the angiographic images.
The injector applies the minimum pressure needed to achieve the programmed flow rate. If the
pressure from the injector exceeds the programmed pressure limit, the system cannot achieve the flow
rate and a Sentinel message displays.
Pressure information can be found in the History tab.
