Measuring and documenting the drainage in the collection chamber-rationale: the nurse should regularly measure and document the amount of chest tube drainage to detect abnormal drainage patterns, such as may occur with a hemorrhage (if excessive) or a blockage (if decreased). continuous bubbling in the water-seal chamber indicates a leak in the closed chest drainage system, which must be corrected. the nurse should keep the collection chamber below chest level to allow fluids to drain into it. the nurse shouldnt strip chest tubes because doing so may traumatize the tissue or dislodge the tube
