5 (30 points) This diagram has two graphs. The one on top is a real spirometry recording. The subject took normal breaths and then was instructed to take in a deep breath followed by blowing it all out. You will notice that the graph seems to slope downward to the right... this often happens in real recordings. Therefore, another drawing was added that stabilized the baseline such that the volume never seems to drop. The axes on the bottom drawing are similar to those in the top graph. Use the drawing numbers to answer these questions. labeled image and drawing of graph from spirometry Question 5 options: This is the total lung volume. This is the tidal volume. This is the air that remains in the airways at all times, even after expiration. This indicates the most air that this person could expire.
