Calculate the minute ventilation from the spirogram assuming the respiratory rate as 12/min
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
1 L/min
2 L/min
4 L/min
6 L/min
