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.

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.

Acute pulmonary edema is an urgent emergency, causing acute respiratory failure because the alveoli (lungs) are filled with fluid, leading to the inability to exchange air (take in O2 and release C02). If detected, diagnosed early, and treated promptly, the disease can recover quickly. If not treated promptly, it will lead to severe acute respiratory failure, with a high risk of death.
