2, according to the use of classification (six categories):
Ventilator
Emergency Ventilator: dedicated to on-site first aid. n Respiratory Therapy Ventilator: respiratory insufficiency of patients with prolonged n Respiratory Therapy Ventilator: Provides prolonged ventilation support and respiratory therapy for patients with respiratory insufficiency. n Anesthesia Ventilator: Dedicated to anesthesia respiratory management. n Pediatric Ventilator: Dedicated to pediatric and neonatal ventilation support and respiratory therapy. n High-frequency Ventilator: Equipped with a ventilation frequency of >60 breaths/min. n Non-invasive Ventilator: Completes the ventilation support through face mask or nasal mask. n
3. Classified by the driving method (three categories): Pneumatic Air-Controlled Ventilator: Both ventilation source and control system are powered by oxygen alone. Pneumatic air-controlled ventilator: the ventilation source and control system are only oxygen as the power source. Mostly portable emergency ventilators. Electric control ventilator: ventilation source and control system are powered by the power supply, internal cylinders, piston pumps, etc., the function of the simpler ventilator. Pneumatic electronically controlled ventilator: the ventilation source is powered by oxygen, and the control system is powered by power. The mainstream design of multi-function ventilator.
4, according to the ventilation mode classification (four categories): Timing ventilator (time switch): according to the preset time to complete the expiratory and inspiratory conversion. n Fixed capacity ventilator (capacity switch): according to the preset output volume to complete the expiratory and inspiratory conversion. n Constant pressure ventilator (pressure switch): according to the preset value of the pressure of the airway to complete the expiratory and inspiratory conversion. n Constant flow of the ventilator (flow rate switch): according to the preset value of the flow rate of the gas to complete the expiratory and inspiratory conversion. Constant-pressure generator: The driving pressure of the ventilation source is low, the pressure is constant during the inspiratory period, and the inspiratory flow varies with the intrapulmonary pressure. n Non-constant-pressure generator: The driving pressure of the ventilation source is low, and varies regularly during the inspiratory period, and the inspiratory flow is subject to the dual influence of the driving pressure and the intrapulmonary pressure. n Constant-flow generator: The driving pressure of the ventilation source is high, and the inspiratory flow varies regularly during the inspiratory period. n Constant-flow generator: The driving pressure of the ventilation source is high, and the inspiratory flow is subject to the dual influence of the driving pressure and the intrapulmonary pressure. n Constant-flow generator : ventilation source drive pressure is high and airflow is constant during the inspiratory phase. n Non-constant flow generator: ventilation source drive pressure is high and airflow changes regularly during the inspiratory phase. n Pressure generators are used for patients with normal lung function, and flow generators are used for patients with poor lung compliance. n
