Overview

  • Long (6-8cm), wide bore (6-9 Fr) single lumen catheter typically placed in a central vein
  • Have wide plastic hub on proximal end with one-way valve
    • Can be used to insert triple lumen catheter, Swan-Ganz catheter, and temporary external pacing wires
  • Commonly used for rapid fluid or blood administration (especially in trauma resuscitation)
    • Can infuse ~600ml/min with pressure[1]
  • Cordis and MAC are both trade names commonly used for sheath introducers
