150ml o2 consumption?

10lit total vanetilation

frc = erv + rv

erv = vital capacity - (tidal volume + ins rv)the one in brackets is ins capacity

erv = 3 - 2 = 1

4.5 = 1 + rv

so rv = 3.5 hey that is soo much. is it right?

1.?

2. RV=4.5-3= 1.5L

3.oxygen consumption= 6/.097-.047=6/.05=120

  #4

1.total ventilation=20/m x .5L=10L

  #5

sorry, RV= 4.5-1=3.5L

  #6

1 & 2 are right

but 3 is wrong
