The nursing method during ventilator treatment is mainly manual airway management, and manual airway management mainly includes: 1. effective aspiration: normal people secrete sputum every day, and sputum is secreted at any time, so if there is sputum in the airway, the nurse should clean it in time, that is, aspiration; 2. respiratory humidification: when breathing normally, the air enters the lungs through the mucous membrane of the nasal cavity and the pharynx, and in this process it is all humidified by its own The air is humidified by the system. After the ventilator, this process is no longer, are going directly into the lungs, so in the process of ventilator treatment, pay attention to the airway wetting care. This care is monitored daily by special people, because the nurses in the respiratory department, especially in the medium and critical ICU are strictly trained and screened; 3. Patients on the ventilator are somewhat uncomfortable, so we must prevent patients from accidental extubation care; 4. Pay attention to airway injury. As the patient is awake, there is a certain confrontation to the ventilator, especially when the ventilator and human-machine cooperation is not good, it is easy to lead to airway hypertension, airway hypertension pressure is too high, may be complicated by pneumothorax and other lung injury, to pay attention to care. Also pay attention to patient safety. Therefore, airway care is very important for patients on ventilators.
