Recently on the surgical unit I work one of the surgeons gave a short inservice on chest tubes. It stemmed from an incident he had with a nurse whom he thought was managing one incorrectly. He told us that if there is bubbling in the waterseal chamber it is ok because the patient has an airleak in the chest-the reason for the chest tube in the first place. I had thought that if the waterseal chamber bubbled it was due to an air leak in the tube or the collection system (we use atrium), and that we needed to assess where the leak is coming from, stop it if possible or call MD. We only get the occasional chest tube on the unit any way so I don't know what to think. The nurses I work with feel the same way I do. Advice???
