Lesson excerpt ยท Assessment not included

Why tip location matters

The single most important determinant of safe central venous access is correct catheter tip position. The target for a PICC or CVAD is the lower third of the superior vena cava (SVC) at or near the cavoatrial junction (CAJ). A tip too high risks thrombosis and malposition; a tip in the right atrium risks arrhythmia and perforation. Intracavitary ECG (IC-ECG) lets the clinician confirm tip position in real time at the bedside, reducing the need for a confirmatory chest x-ray and allowing immediate adjustment before the procedure ends.
