The expiratory phase mixed gas contains various gas components such as carbon dioxide, oxygen, nitrogen and the like, contains various pathogenic bacteria and microorganisms, most of the pathogenic bacteria are filtered and removed through an artificial nose of an anesthesia machine loop, and the carbon dioxide is absorbed by a soda lime tank and then discharged into an anesthesia machine waste gas absorption system, so that the patient is effectively protected, the pathogenic bacteria are prevented from being repeatedly inhaled, the examination participants are protected, and high-risk body fluid secretions such as aerosol, spray and the like inhaled into the patient end are prevented.
An air suction phase: as shown in figure 5, the high frequency jet ventilation is started, the anesthesia machine is started to supply oxygen, the high concentration oxygen and the high frequency jet air are wrapped by the Venturi effect to flow into the artificial ventilation channel to bring the benefit of high oxygenation for the patient, the Venturi effect shows that the flow rate of the fluid is increased when the limited flow passes through the reduced flow section, and the flow rate is inversely proportional to the flow section. While it is known from bernoulli's law that an increase in flow velocity is accompanied by a decrease in fluid pressure, a common venturi phenomenon. Colloquially, this effect is the creation of low pressure in the vicinity of a high velocity flowing fluid, thereby creating an adsorption effect.
