Activity 1: Measuring Respiratory Volumes and Calculating Capacities
Data: Complete the table below.
Chart 1: Respiratory Volumes and Capacities                        
Radius (mm)   Flow (ml/min)   TV (ml)   ERV (ml)   IRV (ml)   RV(ml)   VC (ml)   FEV1(ml)   TLC(ml)
                        
                        
                        
                        
                        
                        
Questions: ?answer each question; use full sentences; ask instructor if you need help
1-1: When you forcefully exhale your entire expiratory reserve volume, any air remaining in your lungs is called the residual volume (RV). Why is it impossible to further exhale the RV (that is, where is this air volume trapped, and why is it trapped)?
1-2: How do we measure a person’s RV in a laboratory?
1-3: What would be an example of an everyday respiratory event that the ERV button simulates?
1-4: What additional skeletal muscles are utilized in an ERV activity?
1-5: What was the FEV1 (%) at the initial radius of 5.0 mm?
1-6: What happened to the FEV 1 (%) as the radius of the airways decreased? How well did the results compare with your prediction?
1-7: Explain why the results from the experiment suggest there is an obstructive, rather than a restrictive pulmonary problem.
1-8: What test is used to distinguish between an obstructive and restrictive lung disease?

Summarize: ? write at least two complete sentences on what you observed by doing this experiment – think “big picture”

can somebody upload exercise 7 activity 2 and 3 charts..plzz...getting confused with the results???

thank you guys for all of your help. this has really helped me in the lab!! :-X :-X :-X :-X :-X

 Patient having an acute asthma attack, the FEV1 (%) decreased

Thank you!  ;D

Thank you for providing all of this information!

Thanks! This helped so much.

Does anyone have the screen shot for the chart 2- Spirometry results and Chart 3- Effect of Surfactant and Intrapleural Pressure on Respiration?

Thanks, you're awesome
