I work in a hospital as a respiratory therapist. Part of my job is mechanically ventilating people. A good guideline is 5-12 ml/kg for adults and 5-10ml/kg for infants and children. This is based on their ideal body weight (IBW). So an average adult is about female is about 70kg. Lets use 8ml/kg that would mean her lung capacity or tidal volume is approx. 560ml (70kg x 8ml/kg). So a child that is 60lbs would be around 27kg. If we use 8ml/kg to figure out their tidal volume it would be 216ml. Total lung capacity would likely be slightly more since we have a residual volume of air that we breath out only when we use force to exhale.

what is the average lung capacity
The average lung capacity is 26 oz. of oxygen.
1,000,000 ml. the largest ever recorded was by kim marello in the year 0f 97' it was 123,000,0000
