What determines the amount of negative pressure transmitted to the patient by suction (in a self-contained, disposable chest drain)?

The one that will be in charge of providing this is the dial setting located on the suction control of the chamber. The disposable chest drainage system is normally used for draining different types of liquid inside the body that may be causing the patient to become uncomfortable. The chest drainage system is used in order to get rid of blood, fluid, and even air. The areas that this reach are usually the esophagus, the lungs, and the heart.

The edge of this is usually located at the pleural space. This is in the chest cavity. Improper chest drain insertion can cause more harm than good to patients so it is best that medical professionals know exactly what they are doing.
