4. Chest tubesA catheter placed through the thorax to remove air and fluids from the pleural space or to prevent air from reentering or to reestablish intrapleural and intrapulmonic pressures
5. Pneumothorax A pneumothorax is a collection of air in the pleural space.
External air enters pleural space
Hole in chest wall or Hole in pleura
Negative pressure is disrupted
? COLLAPSED LUNG
6. NEGATIVE PRESSURE
Vacuum that keeps lung expanded
POTENTIAL CAUSES:
Trauma
Surgery
Bronchoscopy
Central line placement
7. Hemothorax An accumulation of blood and fluid in the pleural cavity between the parietal and visceral pleura.
POTENTIAL CAUSES:
Usually due to a trauma
Can be caused by open chest procedures
8. Chest Drainage Unit Collection chamber
Water seal
Suction control One type is the closed drainage system in a single chamber. The chamber serves as both collector and water seal.
Another type is the two-chamber system that permits liquid to flow into the collection chamber as air flows into the water-sealed chamber.
A newer type is the dry chest tube system that does not use water in the suction chamber. The automatic control valve (ACV) continuously balances the force of the suction with the atmosphere.

-Fluctuations occur with respirations
INSPIRATION (Increased negative pressure in pleural space) = INCREASE IN WATER LEVEL
EXPIRATION (Decreased pressure in pleural
space) = DECREASE IN WATER LEVEL
-As Lung re-expands, fluctuations will decrease
-Obstructed tubing can cause fluctuation to stop
11. BUBBLING IN CHAMBER
Intermittent:
Pleural space leaking air
Resolves with re-expansion
Continuous:
System leak
v connections
Notify MD if unable to find leak
