Any help would be appreciated
Activity 1 - Measuring Respiratory Volumes and Calculating Capacities
Explain why the results from the experiment suggest that there is an obstructive, rather than a restrictive, lung problem?
Activity 2 - Comparative Spirometry
What lung values changed (from those of the normal patient) in the spirogram when the patient with emphysema was selected? Why did these values change as they did?
Which of these two values changed more for the patient with emphysema, the FVC or the FEV1?
What lung values changed (from those of the normal patient) in the spirogram when the patient experiencing an acute asthma attack was selected? Why did these values change as they did?
How is having an acute asthma attack similar to having emphysema? How is it different?
Describe the effect that the inhaler medication had on the asthmatic patient. Did all the spirogram values return to “normal”? Why do you think some values did not return all the way to normal?
How much of an increase in FEV1 do you think is required for it to be considered significantly improved by the medication?
With moderate aerobic exercise, which changed more from normal breathing, the ERV or the IRV?
Compare the breathing rates during normal breathing, moderate exercise, and heavy exercise.
Activity 3 - Effect of Surfactant and Intrapleural Pressure on Respiration
True or False: Surfactant is often added to the lungs of a very premature infant in a hospital in order for her/him to be able to breathe better.
In this lab simulation, when the valve on the left side of the glass bell jar was opened, the total airflow decreased to about ________ ml/minute.
What effect does the addition of surfactant have on the airflow?
Why does surfactant affect airflow in this manner?
What effect did opening the valve have on the left lung?
What effect on the collapsed lung in the left side of the glass bell jar did you observe when you closed the valve?
What is the name of the emergency medical condition that opening the left valve simulates?
When you clicked the “Reset” button, the air was drawn out of the intrapleural space and the lung returned to its normal condition. What emergency procedure would be used to achieve this result if these were the lungs in a living person?
What do you think would happen when the valve is opened if the two lungs were in a single
large cavity rather than separate cavities?
Thank you!
