- - - - 1. Drainage collection chamber
        -The chest tube connects to a 6 foot connection tube that leads to the drainage collection chamber.
        -If the chamber fills, just get a new CDU.
      - 2. Water seal chamber
        -The water seal promotes one-way flow out of pleural space to prevent air from moving back in.
        -The drainage chamber and water seal chamber are connected by a small tube that allows drainage to remain in the first chamber and air too go down into the water of the water seal chamber.
        -Bubbling in the water seal chamber when client coughs/sneezes/exhales is normal.
        -Slight rise/fall of water in the water seal chamber as the client breathes (tidaling). This is normal. When tidaling stops it usually means the lung has re-expanded.
      - 3. Suction control chamber
        -If suction is needed to remove the fluid/air, the chamber controls the amount of pressure applied.
        -Sterile water placed in this chamber up to 20cm line. This is usually the prescribed amount.
        -Turn on the wall vacuum suction until slow, gentle, continuous bubbling.
