CHEST DRAINAGE SYSTEMS

Page 2: Chest Drainage

Normal Breathing Mechanism Operates on the principle of negative

pressure Pressure in the chest cavity is lower

than the atmosphere, causing air to move into the lungs during inspiration.

When chest is opened, there is loss of negative pressure which can collapse a lung.

Chest Drainage Systems

Crucial intervention for improving gas exchange and breathing

Chest drainage therapy involves the removal of air, blood, pus, or other secretions from the chest cavity.

Installing a chest drainage tube can be either an emergency or a planned procedure.

Removing air or fluids from the chest involves the insertion of a tube through the skin and the muscles between the ribs, and into the chest cavity.

This cavity is also called the pleural space.

Page 4: Chest Drainage

Who May Need One

Conditions that may need to be treated by chest drainage therapy include:

Emphysema Tuberculosis spontaneous pneumothorax that causes

more than a 25% collapse of the lung. cancer that causes excessive secretions

Page 5: Chest Drainage

Who Needs One Continues

Emphysema (pus in the thoracic cavity) Hemothorax (blood in the thoracic cavity). In cases where the lung is collapsed,

removing fluids by chest drainage therapy allows the lung to reinflate.

Oftentimes an x ray is performed prior to treatment to determine whether the problem is either fluid or air in the pleural space.

Types of Chest Tubes

Small-bore One way valve apparatus to prevent air

from moving back into the patient Inserted through small incision

Large-bore Usually connected to a chest drainage

system to collect any pleural fluid and monitor for air leaks.

Chest Drainage Insertion

Most patients are awake when the chest drainage tube is inserted.

They are given a sedative and a local anesthetic.

Chest drainage tubes are usually inserted between the ribs.

The exact location depends on the type of material to be drained and its location in the lungs.

Continued

The chest drainage system must remain sealed to prevent air from entering the chest cavity through the tube.

One commonly used system is a water-seal drainage system, comprised of three compartments that collect and drain the fluid or air without allowing air to backflow into the tube.

Once the tube and drainage system are in place, a chest x ray is done to confirm that the tube is in the right location, and that it is working.

Types of Drainage Systems

Traditional water seal 3 chambers, collection, water seal

(middle) and wet suction control Requires sterile fluid be instilled into

water seal and suction chamber + and – pressure release valves Intermittent bubbling indicates

system is functioning properly

Page 12: Chest Drainage

Types Continued

Dry suction water seal 3 chambers like traditional Requires sterile fluid be instilled in water

seal chamber at 2-cm level No need to fill suction chamber with fluid + and _ pressure release valves Indicator to signify suction pressure is

adequate Quieter than traditional

Page 13: Chest Drainage

Types continued

Dry suction One way mechanical suction that allows air

to leave the chest and prevents from moving back into chest

Also referred to as one way valve system No need to fill suction chamber with fluid,

can be set up quickly in emergency Works even if knocked over, great for

ambulatory patients

Special Considerations

Newborns may develop multiple pneumothoraxes requiring multiple chest tubes.

Units have smaller collection chambers and finer calibrations to allow more accurate measurement of small drainage volumes.

The connecting tube has a narrower diameter to allow connection to the smaller chest tubes used in these patients.

Page 16: Chest Drainage

Nursing Management

Ensure drainage tubing does not kink, loop or interfere with the patient’s movements to prevent fluid back up into the pleural space or impede drainage.

Assist patient with range of motion to reduce post op pain and prevent ankylosis of the shoulder.

Milk tubing in direction of drainage system as needed to prevent tubing from becoming obstructed by clots and fibrin.

Page 17: Chest Drainage

Nursing Management Continued Make sure there is fluctuation (tidaling) of

the fluid level in the water seal chamber, shows effective connection

Fluid fluctuations in the water seal chamber or air leak indicator are will stop when Lung has reexpanded Tubing is obstructed Lop of tubing hangs below rest of tubing Suction motor or wall suction is not working

Page 18: Chest Drainage

Nursing Management Continued Monitor for air leaks to prevent tension

pneumothorax. Notify MD if excessive bubbling in water

seal chamber not due to external leaks. Assess for rapid and shallow breathing,

cyanosis, pressure in chest, symptoms of hemorrhage to significant changes in VS

Encourage deep breathing a coughing to help aisle pleural raise and promotion of accumulated fluid in pleural space.

Page 19: Chest Drainage

Nursing Management Continued Keep system below chest level Keep suction at prescribed level Keep air vent open when suction is off. Never let the drainage tube dangle. As

part of your routine care, make sure it's coiled on the bed.

Page 20: Chest Drainage

Nursing Management Continued Pneumothorax, expect little if any output

because the tube is draining air, not fluid. Hemothorax, a lack of drainage may indicate

a clot obstructing the tube. If that occurs, try milking the tube: Starting at the proximal end, gently squeeze and release it between your fingers along the length of the tubing.

However, don't “strip” the chest tube, which means squeezing the length of the tube without releasing it. Once a common practice, stripping the tube causes a dangerous increase in intrathoracic pressure and doesn't lead to any significant increase in output.
