1. Transferring fresh gas (common gas) containing or not containing anesthetic gas to patient;
2. Absorbing the CO2 that is exhaled by the patient and transferring the generated O₂ to the patient;
3. Providing a passage to control the patient's inhaling and exhaling;
4. Exhausting the excessive gas and waste gas.

 

4.6.2 Structure

Anesthesia ventilation system mainly comprises: Breathing Bellows; inhalation and exhalation flappers; CO2absorbent; "MC-AC" selection valve; "APL" valve(adjustable pressure limiting valve, exhaust valve); excessive gas discharge port etc.

Fig 5Anesthesia ventilation system Inhalation flapper and exhalation flapper Inhalation flapper (1) and exhalation flapper (2) are one-way valves controlling direction of respiration gas flows.
These flappers consist of: flapper hood (1),(2), flapper disk (3),(4)
With respiratory movement of patient, inhalation flapper disk and exhalation flapper disk open and close alternative, when the patient.
 

• nhales, inhalation flapper disk opens and exhalation flapper disk closes, so that gas output by breathing circuit system passes breathing pipeline and enters patient respiratory tract;
• exhales, inhalation flapper disk closes and exhalation flapper disk opens, so that gas exhaled by patient passes breathing pipeline and enters breathing circuit system.

 

4.6.3 CO₂absorbent(cycle absorbent assembly)

 

• Functions

CO₂absorbent contains CO₂ absorbent. The absorbent can absorb the patient's exhaled gas, and transfer the generated O₂ to the patient.

• Structure

CO2 absorbent is installed at bottom of the anesthesia ventilation system, composed of absorbent housing, screen, and internal sleeve. The capacity of this equipment CO₂ absorbent is approx. 2000mL. Capacity of CO₂absorbent of this equipment is about 2000mL.

"MC-AC" selection knob To select manual ventilation (bag) or mechanical ventilation (ventilator). When

• "MC-AC" selection knob is turned to "   ", the patient's breathing is controlled manually;
• "MC-AC" selection knob is turned to "   ", the patient's breathing is controlled by the ventilator.

"APL"valve (adjustable pressure limit valve, exhaust valve)

"APL" valve is used for adjusting the pressure limit value of the anesthesia ventilation system during manually controlled ventilation. When the pressure in the system exceeds the limit value, the pressure is relieved by the excessive gas exhaust port.

• Turn clockwise of the "APL" valve knob increases the pressure limit value of the respiratory system. When turning clockwise to the end, the valve closes, and the pressure limit value is approx. 7.0kPa then;
• Turn counterclockwise of the "APL" valve knob decreases the pressure limit value of the respiratory system. When turning counterclockwise to the end, the "APL" valve opens completely, and the pressure limit value is approx. 0.04kPa then, gas in the respiratory system is exhausted directly through excessive gas exhaust port.
