Researches on artificial lung simulators

With the wide clinical use of the ventilator, much attention has been paid to its safety and efficiency. To avoid harming to the patient, any ventilator must be functionally tested before it being used to treat the patient. Lung simulator is just the dedicated equipment used to test and calibrate the ventilator. The paper mainly introduced this equipment including its principle, representative products and comparison between different lung simulators, so that the doctor or the nurse can wholly learn the lung simulator, and give guidance to learn how to test the ventilator.
