Is the artificial lung the same as the ventilator?

Artificial lungs are not the same as ventilators. Artificial lungs are actually oxygenators that work outside the body to replace lungs, taking in oxygen and expelling carbon dioxide. Artificial lungs can be used clinically for some severe respiratory failure and can be used as a treatment for excess. The ventilator still needs to use the lungs to work. The ventilator plays an auxiliary role. It can send high concentrations of oxygen to the lungs. In addition, it can assist a certain pressure to help the lungs work. For many patients with respiratory failure, the application of ventilator treatment may be sufficient, but some severe respiratory failure, the application of ventilator treatment, the patient's hypoxia still can not be improved. In this case, artificial lungs can be considered to replace the lungs to work.
