For peripheral IV catheter insertion, at what angle is the catheter typically inserted?

Explanation:
Entering a peripheral vein with the catheter at a shallow angle helps you align with the vein and minimize tissue trauma. The typical starting angle is about 15–30 degrees to the skin. This range is shallow enough to enter the vein without puncturing the back wall or skimming through surrounding tissue, yet steep enough to find and cannulate the vein reliably. If you go in too steeply, you risk puncturing the far wall or causing more trauma; if you go in too shallowly, you may miss the vein altogether. Once you see blood return, you can lower the angle as you advance the catheter to seat it smoothly within the vein.
