Chest tubes are indicated when the normally airtight pleural space has been penetrated through surgery or trauma, when a defect in the alveoli allows air to enter the intrapleural space, and when there is an accumulation of fluid, as from pleural effusion. The effect of excessive amounts of air and fluid within the pleural space is collapse of the lung and the danger of mediastinal shift.
Chest tubes may be connected to a variety of closed drainage systems: a water-seal drainage system with one, two, or three bottles; and a self-contained system such as Pleur-evac. Whatever the type, the purpose of the system is to allow for drainage from the pleural cavity to the outside and at the same time prevent the entry of atmospheric air into the pleural cavity.
Precautions that must be taken in the maintenance of the drainage system are:
1. The bottles and collection apparatus of the system must be kept below the level of the chest to prevent backflow.
2. The lumens of the tubes must be kept open to allow for drainage. If they are obstructed there will be no fluctuation of the fluid level in the glass tube that is connected to the chest tube at one end and kept under water in the bottle at the other end. In the Pleur-evac, the liquid in the chamber should rise on the right side and fall on the left side. If there is evidence that the system is not working properly, this must be attended to immediately. Occlusion of the tubes can lead to a buildup of air and fluids in the pleural cavity and creation of a tension pneumothorax.
3. The system must be a closed (airtight) system. There can be no leaks around connections, and the lower end of the glass tube must remain under water in the bottle.
The amount, color, and consistency of the fluid drainage should be checked at least once each hour for the first 24 hours after surgery. The chest tubes should be milked and stripped every one to two hours to assure patency and adequate drainage. The amount of air being removed is indicated by occasional bubbling in the water-seal chamber. Excessive bubbling may indicate air leaks in the tubing.
An important aspect of patient care is proper positioning to maintain adequate drainage. The positions allowed and the amount of mobility permitted will depend on the patient's surgical diagnosis, the placement of the tube(s), and preference of the attending physician. Frequent turning, coughing, and deep breathing are instituted on a regular basis to avoid serious pulmonary complications. An exception to the rule of turning is the pneumonectomy patient, who is placed in high Fowler's position and not turned for at least 24 hours after surgery. Chest physical therapy and intermittent positive pressure breathing (IPPB) treatments usually are ordered for all patients with chest tubes. Some patients may require a ventilator during the immediate postoperative period.
The patient is observed for signs of respiratory distress and a buildup of air and fluid within the pleural cavity. Early correction of this condition can prevent mediastinal shift. Other signals that demand immediate attention are persistent bubbling in the underwater seal (fluid should fluctuate in the tube as the patient breathes), a drainage through the tube that accumulates at a rate of more than 100 ml per hour, leakage of air at the junctions of the chest tube and tubing and bottles or self-contained unit, and a “putty” appearance caused by the leakage of air into subcutaneous tissues in the upper chest and neck. After a chest tube is removed, the wound is promptly sealed with a sterile petroleum jelly dressing to occlude the opening and prevent entry of air into the pleural space.

Patient discussion about chest
Q. I was in the ER because of a chest pain and the doctor there said its costochondritis. What does it mean? I am a 42 years old man. Last night i went to the ER because of a chest pain. The doctors there did many test and in the end they said its costochondritis. What does it mean? Can someone elaborate about the risk factors that can cause this symptom?
Q. I still have chest pain after 5 angioplasties/stents. Does anybody else still have that much angina?
Q. What is the differential diagnosis of chest pain in a 35 year old woman? I am a 35 years old woman. I suffer from chest pain for about 24 hours. I just came back from a trip to Europe, and i feel really bad. I smoke and I take anti contraceptive and i know that I am at a risk for pulmonary embolism or costochondritis. Cat it be something else?
It can start in costochondritis if u carried a lot of luggage or might be pulmonary embolism if you didn't move from the chair all the flight. But it can also be a sign for an acute coronary syndrome (even at the age of 35) or a pericarditis. To be sure you need to consult with your GP.
