Vascular access types
- Central venous catheterization
- 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.[1]
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: 7.6 L/hr
- 8.5 Fr Cordis with pressure bag: 20.0 L/hr
