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 concentration
Maximum alveolar concentration
Maximum analgesic concentration
Minimum analgesic concentration
Ans. is 'a' i.e. Minimal Alveolar concentration Minimal alveolar concentration (MAC)"is 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
