flow and decrease the risk of phlebitis. Inserted at bedside (typically by a
nurse) and only local anesthesia is required.

inserted through the skin directly into a central vessel; High Risk for
complications; Used in cases of emergencies and inserted into subclavian or
jugular vein (or femoral)
*Types of Central Lines:* Tunneled Catheter Right Ans - A catheter that is
tunneled through the skin and subcutaneous tissue to a central vessel; the
entrance point of the catheter is distant from the entrance to the vascular
