Hi, I am an ICU nurse in Australia, and where I work we are currently looking at introducing coloured caps for our central lines. Our plans are Blue caps = general use. White Caps = Emergency access port. Red Caps = Don't use (For arterial lines and blocked lumens). I am just interest if any other units have a simular system. Also what policies are in place for emergency access. At the moment we try and keep our distal lumen free for emergency access. Looking forward to your replys. Thanks.
