The following questions refer to Activity 2: Examining the Effect of Changing Airway Resistance on Respiratory Volumes.
4. How did changing the radius effect FEV1 (%)?
When decreasing radius you caused a decrease in the FEV1 %
5. What was the FEV1 at a radius of 5.00 mm?
73.9%
6. Do the results suggest that there is an obstructive or restrictive problem? Explain.
There is no problem, the airway is at normal radius.
Simulating Factors Affecting Respirations
The following questions refer to Activity 3: Examining the Effect of Surfactant.
7. What effect does the addition of surfactant have on the airflow?
It causes increased airflow
8. Why does surfactant affect airflow?
It causes reduced surface tension in the alveoli, so the alveoli can expand more.
9. Why do premature infants have difficulty breathing?
They don’t have enough surfactant
The following questions refer to Activity 4: Investigating Intrapleural Pressure.
10. What effect does opening the valve have on the left lung? Why does this happen?
It collapses cause intrapleural and atmospheric pressure are the same.
11. What condition does opening the valve simulate?
Pneumothorax
12. What is the value of the pressure in the left lung when the valve is opened?
0.00
13. What happened to the total flow when the valve was opened?
It was half the flow . Less than when both lungs were working.
14. In the last part of this activity, when the reset button was clicked, what procedure would be used with real lungs?
You would insert a chest tube to remove the air
