Guide Wire

On this page:Troubleshooting


  • No flashback - insert the needle slightly deeper or withdraw slightly and reattempt at a slightly different angle
  • Not pulsating blood - potentially in a vein
  • Unable to advance the guidewire - withdraw the guidewire and make sure that there is flashback of blood. If there is, then gently try to advance the guidewire further. If the guidewire continues to meet resistance then withdraw and start again.
