Needle
- Note: The angle of the needle in this picture would be for more superficial veins; the angle of the needle may change depending on the depth of the vein.
- You may need a longer (1.88 inch) 18 GA needle.
- Needle length is dependent on the depth of the vein and approach.
- This image shows a shallow approach. Usually, the needle is inserted at a 45 degree angle for an Ultrasound-Guided Peripheral Intravenous (USGPIV) insertion.
