All of the following factors decrease the minimum alveolar concentration (MAC) of an inhalational anaesthetic agent except
High-Yield Explanation
MINIMUM ALVEOLAR CONCENTRATION: The MAC of an inhaled anesthetic is the alveolar concentration that prevents movement in 50% of patients in response to a standardized stimulus (eg, surgical incision). MAC is a useful measure because it mirrors brain paial pressure, allows comparisons of potency between agents, and provides a standard for experimental evaluations.
