Residual volume (RV) : IRV + TV + ERV. Pulmonary ventilations : amount of air normally inhaled or exhaled. Expiratory reserve volume (ERV) : volume of air that can be forcefully inhaled after normal inhalation. Spirometer : volume of air that can be forcefully exhaled after normal exhalation. Inspiratory reserve volume (IRV) : volume of air that cannot be forcefully exhaled. Vital capacity (Vc) : vital capacity plus residual volume. Tidal volume (TV) : number of breaths per minute. Respiratory rate : respiratory rate multiplied by tidal volume. Minute volume : measures respiratory volumes. Total lung capacity (TLC) : inspiration and expirations.

15. The following section concerns respiratory volume measurements. Using key choices, select the terms identified in the following descriptions by inserting the appropriate term or letter in the answer blanks. Key Choices A. Dead space volume C. Inspiratory reserve volume (IRV) E. Tidal volume (TV) B. Expiratory reserve volume (ERV) D. Residual volume (RV) F. Vital capacity (VC) 1. Respiratory volume inhaled or exhaled during normal breathing. 2. Air in respiratory passages that does not contribute to gas exchange. 3. Total amount of exchangeable air. 4. Gas volume that allows gas exchange to go on continuously. 5. Amount of air that can still be exhaled (forcibly) after a normal exhalation. 16. Figure 13-5 is a diagram showing respiratory volumes. Complete the figure by making the following additions. 1. Bracket the volume representing the vital capacity and color the area yellow; label it VC. 2. Add green stripes to the area representing the inspiratory reserve volume and label it IRV. 3. Add red stripes to the area representing the expiratory reserve volume and label it ERV. 4. Identify and label the respiratory volume, which is now just yellow. Color the residual volume (RV) blue and label it appropriately on the figure. 5. Bracket and label the inspiratory capacity (IC).
