Hey there! I am a RN fresh out of Nursing School and have been working in the ICU setting for over 2 months now and I have a general question about CT's and UWSD. I am familiar with the UWSD and the proper usage of them as well, but I have a question. Whenever the fluid from the CT begins to "back up" into the tubing, I have a hard time in draining the fluid into the Glass Bottle. The only way that I am able to drain the fluid coming from the CT is to unscrew the top and lift up on the tubing enough to where the fluid begins to drain into the bottle, but not to the point where all of the fluid drains out and allow air to reach inside the CT. Is this an unorthodox practice? If so, what are some other ways that I can drain the fluid out of the CT so that it doesn't back up?
