[{'content': 'Calculate the minute ventilation from the spirogram assuming the respiratory rate as 12/min \nSelect and explain. \nA. 1 L/min, B. 2 L/min, C. 4 L/min, D. 6 L/min', 'role': 'user'}, {'content': 'Answer: D \nExplanation: Ans. (d) 6L/min(Ref: Guyton, 13th ed.P.503)Minute ventilation = tidal volume x respiratory rateHere tidal volume is 500 ml (in the graph, it is seen as 3 L to 3.5 L)So, Minute ventilation =500x12=6L/min', 'role': 'assistant'}]
