Question
Chapter 23.4, Problem 37AYP
Summary Introduction
To describe:
The forced expiratory volume in one second and its clinical importance.
Introduction:
The lungs are the organs involved in the exchange of respiratory gases between atmosphere and body. The efficiencies of the lung functions are measured with the help of different lung volumes and capacities.

Calculate the vital capacity if the inspiratory reserve volume is 3500mL, inspiratory capacity is 4000mL and expiratory reserve volume is 2000mL.
Calculate the expiratory reserve volume and residual volume from the following set of values (EC): Vital capacity 4900ml; total lung capacity 6400ml; inspiratory capacity 3800ml.
Given the following values:
ERV=1700mL
ERV+TAV= 2200 mL
VC= 3000 mL
1) Calculate TAV and IRV.
2) If they have a breathing rate of 14 breaths/min, what is their minute ventilation?
3) If they have the normal dead space ventilation of 150 mL, what is their alveolar ventilation? (show dead space volume as part of the calculation).
4) If they start exercising and increase their breath volume to 1600 mL with 25 breaths per minute, what is their alveolar ventilation now?
