When to Change the Chest Tube Canister
Change the canister in any of these circumstances:
- The fluid level reaches 750cc in any column
- It has tipped over and column levels are uneven (see example below)
- Cracked
- Fluid in blue chamber has turned a different color


In these two examples, measurements are not accurate, and may lead to incorrect management of the chest tube and patient.
When in doubt, change it out.
