trux .. I know the normal tidal volume of an average person would be 0.5 liter or so, the calculator is suggesting 0.65 liters at a respiratory rate of 13 per minute. This is not my question, 0.5 liters is only a fraction of the maximum tidal volume that a person can achive by filling the lungs fully and emptying it to the max as well (residual). So my question is if an average person wants to breath up to 95% of maximum lung volume what would be the tidal volume of such inhale ? would it reach 5 liters or so? or is it much more, coz I assumed that the lungs capacity of an average guy should be around 7 liters no?
