This has proven to be an issue as bedside RN's have had to adjust to the lack of noise in a properly functioning system. The other was to provide an audible confirmation that there was indeed suction being applied to the lung, which would be critical to know in mechanically ventilated patients as the risk of a tension pneumo could be increased in the absence of wall suction. One was, of course, just to provide the "water seal" which was to prevent entrainment of air retrograde up into the pleural space, thus not helping or making a pneumothorax worse. The water seal chamber served two purposes. Sadly this is because they don’t really have a complete understanding of how these systems work so they don’t actually know what the different chambers are for. When facilities switched to the dry suction style with a dial some people got confused when they were told that there would be no more bubbling. This was meant to have continuous bubbling. They used to only have a “wet-suction control” chamber where the amount of suction was controlled by the level to which you filled the chamber with water. Confusion was caused when the Pleur-Evac company developed a “dry suction control” chamber. It will be absent only if there is no longer an air-leak. In general, a chest X-ray should be obtained any time the chest tube is changed from suction to water seal or vice versa.Intermittent bubbling in the water seal chamber will be present if there is still an air-leak regardless of whether it’s on wall suction or not. A stat chest X-ray should be obtained, and the chest tube should be placed back on continuous suction. If, after the transition from suction to water seal, resumption of the air leak is noted, it may indicate recurrence of the patient’s pneumothorax. Once the air leak has stopped, the chest tube should be placed on water seal to confirm resolution of the pneumothorax (water seal mimics normal physiology). The chest tube should initially be set to continuous suction at -20 mmHg to evacuate the air. If the patient has a pneumothorax, air bubbles will be visible in the water chamber called an air leak, these are often more apparent when the patient coughs. The interventional radiologist or surgeon who placed the tube should determine the subsequent frequency of serial chest X-rays required to monitor the location of the chest tube. Respiratory variation in the fluid in the collecting tube, called “tidling,” should also be seen in a correctly placed chest tube, and should be monitored at the bedside to reassure continued appropriate location. Chest tubes are equipped with a radiopaque line along the longitudinal axis, which should be visible on X-ray. Chest tubes are also commonly placed at the end of thoracic surgeries to allow for appropriate re-expansion of the lung tissue.Ī chest X-ray should be obtained after any chest tube insertion to ensure appropriate placement. Pneumothorax and hemothorax usually require immediate chest tube placement. Indications for a chest tube include pneumothorax, hemothorax, or a persistent or large pleural effusion. The third chamber is the collection chamber for fluid drainage. The suction chamber can be attached to continuous wall suction to remove air or fluid, or it can be placed on “water seal” with no active suction mechanism. The water chamber holds a column of water, which prevents air from being sucked into the pleural space with inhalation. The tubes are connected to a collecting system with a three-way chamber. Chest tubes are typically placed between the fourth and fifth intercostal spaces in the anterior axillary or mid-axillary line however, the location may vary according to the indication for placement. They can be as thin as 20 French or as thick as 40 French (for adults). Chest tubes are placed in the pleural space to evacuate air or fluid. The lung re-inflates naturally when this air is withdrawn using the chest drain being inserted here. The lung collapse was done by opening up the pleural cavity to air from outside. The lung was originally collapsed to allow access to the chest organs during surgery. Lung re-inflation after surgery, using a chest drain.
