<prompt> Lowest conc of Anaesthetic agent in pulmonary alveoli needed to produce immobility in response to painful stimulus in 50 individual is termed as:Minimal alveolar concentrationMaximum alveolar concentrationMaximum analgesic concentrationMinimum analgesic concentration  <response>: Ans. is a i.e. Minimal Alveolar concentration Minimal alveolar concentration MACis the lowest concentration of the anaesthetic in pulmonary alveoli needed to produce immobility in response to a painful stimulus in 50 individuals. It is accepted as a valid measure of potency of inhalational general anesthetics - KDT
