  • If lung has up - see indications for removal of chest drain

Tube becomes disconnected:

  • Reconnect tube
  • CXR post reconnection

Tube becomes dislodged:

  • CXR – if persistent pneumothorax can reinsert
  • If no PTX – no need to reinsert drain

Arrhythmia (Tube adjoining cardiac area):

  • Withdraw the chest drain
