The vital capacity= 6000 mL, tidal volume=500 mL and expiratory reserve volume =
1000 mL. What is the inspiratory capacity? Express answer in Liters

Answer

Given

Vital capacity                      = 6000 ml

Tidal volume                      = 500 ml

Expiratory reserve volume = 1000 ml

 

We know that,VC = TV +IRV+ERVSo,IRV = VC - TV-ERVHere, VC = vital capactity = 6000 mlTV = tidal volume = 500 mlERV = expiratory reserve volume = 1000 mlInspiratory reserve volume IRV = 6000-500-1000IRV = 4500 ml

 

 

Now, find the inspiratory capacity,It is the maximum volume of air that can be inhaled following a resting state. ThusIC = IRV + TV    = 4500 ml + 500 ml = 5000 mlIC = 5 litersTherefore, the inspiratory capacity is 5 liters.
