Ventilators help patients breathe when they are unable to breathe on their own for any reason. Although mechanical ventilation has many benefits, patients face some complications such as respiratory infections. Therefore, caring for patients on mechanical ventilation plays an important role in preventing future complications.

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.

Mechanical ventilation is a means of supporting or replacing respiratory function in patients with severe illness. For mechanical ventilation to be highly effective and to achieve the most physiologically appropriate artificial ventilation, the PaCO2 parameter in arterial blood gas must be closely monitored and adjusted within the appropriate range through adjustments on the ventilator.

The nutritional needs of ICU patients are complex. These patients may require adjustments in protein and electrolyte levels. Nutritional issues for patients on mechanical ventilation for long periods of time are particularly important as they affect the patient's ability to recover.
