What this Trial Is About
Volunteers above the age of 18 and below the age of 60 who agreed to participate in the study were not exposed to any interventional intervention other than those routinely applied to the patient during and after the administration of the clinical standard anesthesia protocol. The value indicating the brain's response to hypnotic substances, the vapor concentration in the lung alveoli and the minimum amount of anesthesia gas used will be recorded at certain times. The aim of the researchers in the study was to observe the effect of two different fresh gas flow rates on the amount and cost of waste gas released into the atmosphere.
