I am not an expert in all things IV related so please forgive this probably simple question but need advice. I am to teach a class in the use of cathflo for occlusions. I am comfortable with the PICC lines as have been doing this for some time but have been asked to include ports in the class. This is not something I am comfortable with and have been disappointed that I cannot find much information nor have I been able to get a call back from our rep. If anyone has a step by step poilicy/procedure they would share I would be very grateful- or if you could share any tips I also would appreciate. With PICCS we use negative pressure for most of them but I am very unclear if this is something you can do with a port. Thanks in advance for any assistance.
