The men´s operating room has a capacity of 20 patients in general surgery, which shows that the high rate of patients admitted to this service are due to firearm injury or white weapon and their age is from 14 to 28 years. The high rate of violence exceeds the capacity of this service attending patients with thoracic trauma which are treated with chest drainage system (pleurovac). The purpose of this system is to help the lung to expand and remove fluid that is found in the trauma. But at the time of its management, it has been observed that the patient is not well trained on how to use the drainage system (pleurovac). With respect to the auxiliary nursing staff it is observed that they do not realize how important it is to guide the patients during their respiratory exercises. With this study, we intend to strengthen the auxiliary nursing staff´s knowledge to promote a self-care management process in handling pleurovac and breathing exercises to promote continuity and efficiency dimensions of human quality care.
