4-5: Did the deflated lung reinflate? Explain your answer.

4-6: Why did lung function in the deflated (left) lung return to normal after you clicked Reset?

Summary:
In this Activity, I learned/observed that:  write 1-2 sentences on what you observed by doing this experiment – think “big picture”

SIMULATING VARIATIONS IN BREATHING

Activity 5: Exploring Various Breathing Patterns

Data: No chart necessary here, but you will need to use the data you get from running the experiments to answer the questions below

Questions: answer each question; use full sentences; ask instructor if you need help

5-1: What happens to PCO2 during rapid breathing? Explain your answer.

5-2: What happens to PCO2 during the entire time of the rebreathing activity?

5-3: Did the depth of the breathing pattern change during rebreathing? (Carefully examine the tracing for rate and depth changes; the changes can be subtle). Explain your observations.

5-4: What happened to the PCO2 during breath holding?

5-5: What happened to the breathing pattern when normal respirations resume?

Summary:

In this Activity, I learned/observed that:  write 1-2 sentences on what you observed by doing this experiment – think “big picture”

Activity 6: Comparative Spirometry

Data: No chart necessary here, but you will need to use the data you get from running the experiments to answer the questions below

Questions: answer each question; use full sentences; ask instructor if you need help

6-1: What do you think is the clinical importance of the FVC and FEV1 volume?

6-2: Why do you think the ratio of these two values is important to the clinician when diagnosing respiratory diseases?

6-3: FEV1/FEV x 100% = __________________________

Emphysema Breathing:
6-4: Is the FVC reduced or increased?

6-5: Is the FEV1 reduced or increased?

6-6: Which of these two changed more?

6-7: Explain the physiological reasons for the lung volumes and...
