The main points of care for mechanical ventilation are still relatively numerous and are mainly achieved by nursing specialists, mainly to prevent complications. First, prevention, to avoid air pressure injury, or pulmonary atelectasis, this requires in the respiratory therapist, or well-trained doctors and nurses, according to this specification, the parameters of mechanical ventilation to set a more standardized mode or some parameters. Second, in terms of care is to pay attention to the prevention of ventilator-associated pneumonia, these have a care measures, such as the patient that the head of the bed elevated, elevated 30 °, to maintain airway humidification, regular aspiration, and even do fibrinoscopy, the lungs of some sputum aspiration, and regular culture, according to the results of sputum culture to choose the appropriate antibiotics. Third, other attention should be paid to monitoring, some patients have sputum blockage, airway blockage will occur, timely detection, timely replacement of tracheal intubation, if the tracheal intubation for more than two weeks, tracheotomy to provide a mechanical ventilation support for patients.
