In modern medicine, many advanced equipments are developed to diagnose, care for and treat patients, including mechanical ventilation, which is an activity to support the patient's breathing process. It is necessary to monitor the phenomenon of hypoxia in the blood when using a ventilator for timely treatment.

Patients on ventilators need comprehensive care, combined with monitoring of clinical and paraclinical signs and ventilator parameters. Ventilator patients are often seriously ill, so care and nutrition of ventilator patients must be done properly.

Ventilator-associated pneumonia is one of the most common clinical problems in the intensive care unit, which reduces the patient's prognosis and increases the cost of treatment. Therefore, treatment of ventilator-associated pneumonia requires active prevention, and when faced with a patient with ventilator-associated pneumonia, it is important to optimize antibiotic therapy and comprehensive care.
