The purpose of training on prevention and treatment of ventilator-associated pneumonia is to educate people to use ventilator correctly, and to prevent and control ventilator-associated pneumonia infection. If the ventilator is not properly cleaned, disinfected and maintained, it may lead to cross-infection of bacteria and viruses. In addition, the correct use of ventilator is also very important. If improperly used, it may lead to ventilator-associated pneumonia, especially for the elderly, immunocompromised people, cardiovascular patients, diabetic patients and other high-risk groups. Therefore, it is very important to use ventilator correctly and implement epidemic prevention control measures. This training will introduce the correct use and maintenance methods of ventilators, and educate participants on appropriate prevention and control skills to reduce the spread of ventilator-associated pneumonia.
