To determine the best size, use a flexible measuring tape and have your nurse or a friend measure the circumference of your arm where your PICC is placed. Make sure to have your arm relaxed straight by your side. Once you receive the PICCPerfect, try it on your arm that doesn’t have the PICC line; this will ensure your practice on how to get it on and make sure it will be comfortable on your arm with the PICC. You can also use our sizing app, and check out this video for more tips.
