Vascular access

Vascular access types

• Central venous catheterization
  • Central line: internal jugular
  • Central line: subclavian
  • Central line: supraclavicular
  • Central line: femoral
  • Pediatric central line
  • Sheath introducer
• Rapid infusion catheter
• Intraosseous access
• Venous cutdown
• Umbilical vein catheterization
• Ultrasound assisted peripheral line placement
• External jugular vein cannulation
• The "Easy IJ"
• Midlines

Flow Rates

Flow rate depends on diameter and length of IV; the Hagen–Poiseuille equation.

Peripheral IV

• 16G IV: 13.2 L/hr
• 18G IV: 6.0 L/hr
• 20G IV: 3.6 L/hr

Central Line

• 5 Fr PICC/Port: 1.75 L/hr
• 7 Fr TLC 16G distal port: 1.9 L/hr
• 7 Fr TLC 18G proximal port: 3.4 L/hr
• 12 Fr HD: 23.7 L/hr
• 8.5 Fr Cordis/introducer sheath: 7.6 L/hr
• 8.5 Fr Cordis/introducer sheath with pressure bag: 20.0 L/hr
