Abstract:
Objective To evaluate the accuracy of performance of Engstrom Eas 9010 vaporizerMethods Using Datex Capnomac AS/3 monitored the output of Gambro-Engstrom Eas 9010 anesthetic agent vaporizer under various situations l Determing the output of vaporizer at different gas flow rates of 0 5,1 0,2 0,4 0,6 0 and 8 0 L?min -1 2 The effects resulting from up stream oxygen flushing 3 The effects due to additional nitrous oxide as carrier gas 4 Effects of different airway pressure at the same flow rate Results 1 The output of the vaporizer was highly correlated with the dial setting at various gas flow rate except dial setting was more than 8% and gas flow rate less than 0 5L?min -1 2 Upstream oxygen flush could not decrease the concentration remarkably 3 The output of the vaporizer was not affected by additional carrier gas 4 The effect on vaporizer output was not remarkable under different airway pressure at the same flow rate Conclusions The anesthetic vaporizer principle used in the Gambro-Engstrom Eas 9010 apparatus is innovative Electronically controlled vapor quanta injection is used with safety feed back Its accuracy can't be influenced by temperature,pressure and carrier gas indicating to be safely applied to the low or even minimal flow anesthesia
