Classification of ventilators

In modern clinical medicine, ventilator is an effective means to artificially replace the function of spontaneous ventilation. This article will introduce the relevant knowledge of ventilator, hoping to help everyone.

• Classification of ventilators.

• The company has ventilator products.

Classification of ventilators.

1. Sort by type of use or application

   
   

   
   

   Controlled Mechanical Ventilation Ventilator (CMV) 1. Definition: A patient's breathing produced, controlled, and regulated entirely by a mechanical ventilator in the presence of diminished or absent spontaneous breathing. 2. Application: Spontaneous breathing disappears or weakens due to disease; when spontaneous breathing is irregular or too fast, and mechanical ventilation cannot be coordinated with the patient, artificially suppress or weaken spontaneous breathing.

   
   

   
   

   Assisted mechanical ventilation ventilator (AMV) 1. Definition: A ventilator assists or enhances the patient's spontaneous breathing in the presence of patient breathing. Various types of mechanical ventilation are primarily triggered by the patient's inspiratory negative pressure or inspiratory airflow. 2. Application: Although spontaneous breathing exists and is relatively regular, it is not suitable for patients with weakened spontaneous breathing and insufficient ventilation.

   
   

2. Classification by route of use of mechanical ventilation

   
   

   
   

   Intrathoracic or airway compression type

   
   

   
   

   External chest ventilator

   
   

3. Classification according to the switching mode of inhalation and exhalation

   Constant pressure ventilator: After the pressure in the airway reaches the expected value, the ventilator opens the exhalation valve, and the thorax and lungs collapse passively or exhale from negative pressure. When the pressure in the airway continues to drop, the ventilator passes through again. Positive pressure creates airflow and induces inspiration.

   
   

   
   

   Constant-volume ventilator: The predicted tidal volume is sent into the lungs through positive pressure. After reaching the predicted tidal volume, the air supply is stopped and the expiratory state is entered.

   
   

   
   

   Timing ventilator: supply air according to the pre-designed inspiratory and expiratory times. (4) Hybrid (multi-functional).

   
   

4. Provide air according to ventilation frequency

   
   

   
   

   High-frequency ventilation: ventilation frequency > 60 times/min. 1. Advantages: low airway pressure, low intrathoracic pressure, little disturbance to circulation, no need to seal the airway. 2. Disadvantages: It is not conducive to the elimination of carbon dioxide. 3. Classification: high-frequency positive pressure ventilation, high-frequency jet ventilation, high-frequency oscillatory ventilation.

   
   

   Normal frequency ventilation: ventilation frequency <60 times/min.
