Comparison of Different Ventilator and Vaporizer Technologies to Study Economic and Environmental Implications

Completed · Not applicable

Conditions studied: Anesthetic Gas Consumption and Cost-Effectiveness

In brief

The purpose of this study is to test whether or not the use of a low volume ventilator in an anesthesia machine reduces anesthetic costs significantly as compared to other high volume machines. The study will compare the a low-flow anesthesia machine to a traditional anesthesia machine during routine elective general surgery in patients with ASA ratings of 1-2 under general anesthesia receiving standard care.
