Invasive ventilator: the trachea is cut in the neck, a tube is inserted into it, and a ventilator is attached to this tube to provide ventilation support to the patient.
Non-invasive ventilator: A ventilator that does not require trauma to the body and uses a mask to provide ventilation through the nose, providing a respiratory aid to the patient.
Difference as shown:
Extended information
Ventilator: in modern clinical medicine, the ventilator as an effective means of artificially replacing the function of voluntary ventilation, has been widely used in respiratory failure due to various causes, anesthesia and respiratory management during major surgery, respiratory support therapy and emergency resuscitation, in the field of modern medicine occupies a very important place. The modern medical field occupies a very important position. Ventilator is a kind of medical equipment that can play a role in preventing and treating respiratory failure, reducing complications, saving and prolonging patients' lives.
I. Classification:
1. Controlled mechanical ventilation (CMV)?
2. Assisted mechanical ventilation (AMV)?
3. intrathoracic or airway pressurization type
4. extrathoracic type
5. fixed pressure type: after the pressure in the airway reaches a predicted value, the ventilator opens the expiratory valve, and the thorax and lungs are passively atrophied or expiration is generated by the negative pressure, and when the pressure in the airway continues to fall, the ventilator generates an airflow again by the positive pressure and causes inspiration.
6. Constant volume type: the predicted tidal volume is delivered to the lungs by positive pressure, and when the predicted tidal volume is reached, the air supply is stopped and the expiratory state is entered.
7. Timing type: supply air according to the pre-designed time of inspiration and expiration. （Hybrid type (multi-function type).
8. High-frequency ventilation: ventilation frequency >60 times/min. (1) Advantages: low airway pressure, low intrathoracic pressure, little interference with circulation, no need for airway confinement. (2) Disadvantages: unfavorable to carbon dioxide elimination. ( 3) Classification: high-frequency positive pressure ventilation, high-frequency jet ventilation, high-frequency oscillatory ventilation.
9. Synchronized ventilator: the start of inspiration of the patient's voluntary breathing can trigger the ventilator to supply air to the patient's airway and produce an inspiratory action.
10. Non-synchronized ventilator: the patient's breathing or inspiratory negative pressure can not trigger the ventilator to supply air, generally only used for controlled mechanical ventilation of patients.
11. Infant ventilator
12. Toddler ventilator
13. Adult ventilator
14. Simple ventilator
Two, the development of the application of the current status of the development of the ventilator
1. Today's application of ventilators from newborns to adults, only need to replace the humidifier and the pipeline; mechanical ventilation from non-invasive to invasive, non-invasive ventilation with stronger compensation for air leaks.
2. The addition of Autoflow or flow-by in the volume-controlled ventilation mode increases patient autonomy, reduces airway pressure, increases patient comfort, and overcomes the shortcomings of the volume-controlled ventilation mode.
3. Ventilator delivery response time (30-40ms), delivery waveform (square wave a constant flow, deceleration wave), trigger sensitivity is the flow rate trigger adjustable, abandoned pressure trigger, PSV mode of expiratory sensitivity adjustable.
