Quizplus · Accepted Answer

Wet suction is achieved using a one-bottle system, which consists of one chamber filled with sterile water. The amount of suction is controlled by the amount of water placed in this chamber. As the suction is generated, it generates negative pressure, which draws air and fluid from the chest and into the drainage system. The dial setting on the wall suction does not control the amount of suction in the system. The amount of drainage in chamber three is not a factor in controlling the suction. The negative pressure in chamber two is a result of the suction and not a control mechanism for it.
