What is the working principle of ventilator

A ventilator is a medical device that delivers oxygen and an air mixture to a patient by means of positive-pressure ventilation to maintain the patient's respiratory function, and is used to assist or replace the patient's voluntary respiration. Its principle is through a series of mechanical devices will be air or oxygen gas processing for independent breathing instructions required for the pressure, flow and volume of gas, timely delivery to the patient to carry out the conditioned reflexive respiratory action. A ventilator consists of three main components: the air source, the control/monitoring system and the delivery system. The gas source provides the ventilation gas, the control/monitoring system controls and monitors the patient's breathing, and the delivery system delivers the gas to the patient's airway. When using a ventilator, the parameters need to be set appropriately according to the patient's specific situation, and regular inspections and maintenance should be carried out to ensure the normal operation of the equipment. When using the ventilator needs to be kept clean, and regularly replace the breathing tube and mask and other instruments. In addition, ventilators have certain indications and contraindications, which need to be selected and used according to the patient's specific situation.
