Before undertaking this course, I was aware that air or liquid in the pleural space results in the lungs' collapse. A closed drainage system is applied to remove the fluid, air, or both from the pleural cavity. Moreover, an individual might need a closed chest drainage system when the pleural space's negative pressure is upset, driving in respiratory pain ( Porcel, 2018) . I understood that a closed chest drainage system utilizes suction or gravity to restore the negative pressure and move fluid or air from the pleural cavity to re-expand the collapsed lungs. Any time a chest tube is connected, it must be inserted into a one-way mechanism that permits escape of the air from the pleural cavity and prevents entry of air or fluid from the atmosphere, which can be achieved through an underwater seal mechanism. Taking this course, I was eager to gain more knowledge regarding closed chest drainage.
As per my expectations, I have learned a lot in this course regarding closed chest tube drainage. I have gained vast knowledge about how closed drainage can be performed. The closed chest drainage can be conducted with a three-bottle chest drainage system. However, the traditional three-bottle chest drainage system has been substituted by numerous disposable units that integrate the three-bottle system's conventional functions and incorporate the system into a plastic unit ( Porcel, 2018) . The closed drainage system is hermetically sealed to deflect the atmospheric pressure ( Pickett, 2016) . Because the pleural cavity usually has negative pressure that permits for lung extension, any tube attached should be fixed to prevent liquid or air from entering the hole where the line is connected .
Delegate your assignment to our experts and they will do the rest.
The knowledge I have acquired regarding closed chest drainage will be instrumental in my future nursing career. I am now in a position to explain normal respiration's physiology and describe the closed chest drainage system, waterless system, and water-seal system. I can also make informed decisions and take appropriate measures of maintaining patients' safety during the chest tube insertion and explain the approaches of troubleshooting the chest tube system.
