Procedure - PIV Flashcards
Review the gauges of IV by color.
Orange = 14 G Gray = 16 G Green = 18 G Pink = 20 G Blue = 22 G Yellow = 24 G Purple = 26 G
Most IV tubings have what kind of occlusion device on the line?
Roller clamps or stopcocks
Why do most IV tubes have one-way valves in the middle of the line?
The one-way valves are there to prevent bolused medicines (such as those given through a stopcock or Y-port) from passing back up the line to the fluid bag.
If a line does not have a one-way valve then you need to clamp it to prevent backflow.
With medicines that are in glass bottles, you need to have a ____________ in the line to allow fluid to flow.
vent
Many lines will have a vent in the spike that you can open, but if that’s not the case then use a large bore needle to puncture the bottle.
What is unique about the valves of manifold ports?
Manifold ports have one-way valves in two directions so that fluid can only flow to the patient. A syringe can thus be left on the manifold with no concern that it will get backflushed with fluids or blood.
What pumps can slowly infuse tiny volumes?
Syringe pumps
