I work on a med surg floor. I have a question about chest tube orders. The pt got a CT for a pnuemothorax and when he came back with it the order read: "chest tube to 20cm of H2O pressure. No more than 20cm of water." The first nurse that had the pt put in the 20 cm of water and hooked up to the wall, which by the way I thought was what 20 cm of water pressure meant. The following nurse said that it should not be hooked up to the wall suction because it did not say to. She took it off the wall suction and left it to water seal only with 20cm of water in the chamber and every other nuse after left it like that. When I got the pt it was still like that. I asked my charge nurse and she said it should not be hooked to the wall suction. If any of you frequently work with chest tubes frequently I would appreciate your input. Thank you.
