简要总结
CO2 removal is a mandatory part of modern anesthesia systems. Current chemical absorbers pose problems as the chemical granulate reacts not only with the CO2 but also the anesthetic drugs, producing organ toxic substances. The proposed CO2 absorber provides a solution to the problem of organ-toxin production in anesthetic circuits.
详细描述
CO2 removal is a mandatory part of modern anesthesia systems. Current chemical absorbers pose problems as the chemical granulate reacts not only with the CO2 but also the anesthetic drugs, producing organ toxic substances. The proposed CO2 absorber provides a solution to the problem of organ-toxin production in anesthetic circuits.
This new absorber can be easily integrated into any anesthesia circuit, and can effectively remove CO2 without reacting with anesthetic drugs, thus eliminating organ-toxic by-products.
It uses advanced membrane technology to separate gas flows within the circuit, separating the expensive anesthetic vapors from the CO2 (the main by-product of metabolism). Anesthetic vapors thus remain in the closed loop circuit, while CO2 is separated and exhausted to the atmosphere, rather than being absorbed through a chemical reaction.

结局指标
主要结局
End tidal CO2 level
时间窗: Continuous (5min intervals) over duration of anesthesia. No data collection prior or post anesthesia.
After completion of the surgery, the digital respiration records are exported from the hospital database. End tidal CO2 is assessed as either in range \[4.1-5.6\]% or out of range \<4.1% or \>5.6%.
