China High Flow Ventilator Use In Hospital
In modern clinical medicine, the ventilator, as an effective method that can artificially replace the autonomous ventilation function, has been widely used in respiratory failure caused by various reasons, anesthesia and respiratory management during major surgery, respiratory support therapy and emergency resuscitation. It occupies a very important position in the field of modern medicine.
One. Classified by type of use or application
(1) Controlled mechanical ventilation (CMV) Definition: When the patient’s spontaneous breathing weakens or disappears, the mechanical ventilator generates, controls and regulates the patient’s breathing completely. 2. Application: When the spontaneous breathing caused by the disease disappears or weakens; when the spontaneous breathing is irregular or too fast, and mechanical ventilation cannot coordinate with the patient, artificial methods are used to suppress or weaken spontaneous breathing.
(2). Auxiliary mechanical ventilation (AMV) Definition: In the presence of patient breathing, the ventilator assists or enhances the patient’s spontaneous breathing. The various types of mechanical ventilation are mainly triggered by the patient’s inspiratory negative pressure or inspiratory airflow. 2. Application: Although spontaneous breathing exists and is more regular, it is not suitable for patients with weakened spontaneous breathing but insufficient ventilation.
