When your doctor says you need a PICC line, a special PICC line nurse will come and meet you in your room.

The first thing they will do is look at your arm to find just the perfect spot for your new PICC line.

They will put a tourniquet on your arm, which helps the nurse see your veins. A tourniquet feels like a tight squeeze or hug on your arm.

The nurse will then put a cold gel on your arm and use an Ultrasound machine to see the veins inside your arm. The part that touches your arm has a rounded end and does not hurt.

This is what an Ultrasound machine looks like.

You can see a picture of your veins on the screen of the Ultrasound machine if you want. After they find just the right spot, the nurse will mark the spot on your arm with a marker.

Then they will measure your arm and chest so your PICC line is the perfect size just for you.
