ultrasound IVs: triangle tip

23 Sep

Nice little tip for your ultrasound-guided IV (PIV or central) procedure:

 

Make your needle insertion site the same distance from the probe as the depth (distance from skin) of the vessel.  

Make your angle of approach 45 degrees.  

iv1

iv2

Thanks to Pythagoras, you should be able to get to the vessel this way.

 

QUICK RECAP:

Insertion site distance = depth of vessel from skin

angle of approach = 45 degrees

hurrah, math!
