🔌Bubbling in the suction control chamber indicates that suction is actively being applied. If there is no bubbling, the first action should be to check whether the suction regulator is turned on and functioning properly.

🧠This step ensures that the system is receiving the ordered amount of suction, which is essential for proper lung re-expansion and drainage.

📞Notifying the provider is premature unless the issue persists after verifying the equipment, as nurses must first assess the equipment setup.

👀Continuing to monitor without action is inappropriate if bubbling is expected and absent—this may indicate ineffective suction.

🧪Milking the chest tube is not a routine action and can cause increased intrathoracic pressure or tissue damage—it should be done only if prescribed and after confirming the cause of the issue.

📌Core Message

When expected bubbling is absent in a chest tube's suction chamber, the nurse must first verify that suction is on before taking further action.
