Data

Activity 1

Data Table 1: Assessing Respiratory Rate (RR) at Rest

Trial 1	Trial 2	Trial 3	Trial 4	Average number of breaths per minute

Activity 2

Data Table 2: Assessing Respiratory Rate (RR) After Activity

Trial 1	Trial 2	Trial 3	Trial 4	Average number of breaths per minute

Compare the values for breathing while at rest sitting vs. breathing while at rest standing. Is there a difference? Why or why not?

Activity 3

Data Table 3: Assessing Tidal Volume (TV)

Total Volume (L)	Tidal Volume (L)

Activity 4

Data Table 4: Assessing Expiratory Reserve Volume (ERV)

Total Volume (L)	Expiratory Reserve Volume (L)

After expelling the expiratory reserve volume, did any air remain in your (or the subject’s) lungs? Explain your answer.

Activity 5

Data Table 5: Assessing Vital Capacity (VC)

Estimated Vital Capacity (L)	Measured Vital Capacity (L)	Optional: Average Measured Vital Capacity (L)

Activity 6

Data Table 6: Calculating Inspiratory Reserve Volume (IRV)

Measured Vital Capacity (L)	Tidal Volume (L)	Expiratory Reserve Volume (L)	Inspiratory Reserve Volume (L)

Activity 7

Data Table 7: Assessing Peak Expiratory Flow Rate (PEFR)

Trial 1 (L/min)	Trial 2 (L/min)	Trial 3 (L/min)	Trial 4 (L/min)	Average PEFR (L/min)

IRV and PEFR are often measured in individuals who may have asthma. Based on the Background for this investigation, and your experience carrying out Activities 6 and 7, how would you expect these values to be affected by asthma?
