Pre-laboratory Questions
1.
What is the danger associated with hyperventilation? When someone is hyperventilating, their blood carbon dioxide level drops to a dangerously low level. Because of this, blood flow to the brain slows down because the airways get narrow.
2. Calculate the vital capacity when the Tidal Volume is 3.0 liters, the
Inspiratory Reserve is 2.8 liters, the Expiratory Reserve is 1.0 liters, and
the Residual Volume is 1.4 liters.
The calculation is VC = IRV + ERV + TV = 2.8 + 1.0 + 3.0 = 6.8 liter.
3.
Calculate your estimated Vital Capacity.

1.
Compare the values for breathing while at rest sitting vs. breathing while at rest standing. Is there a difference? Why or why not?
Their
breathing rate was slower when they were at rest than when they were working hard. Given its normal speed, measuring at rest is more accurate.

2.
After expelling the expiratory reserve volume, did any air remain in your (or the subject’s) lungs? Explain your answer.
Oxygen usually remains in the lungs after you breathe out, thus the person's lungs had some air.

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?
Asthma patients may have lower rates due to their inability to expel out as much oxygen.

Post-laboratory Questions
1.
Explain what you would expect to see happen to the PEFR in someone
who smokes.
Since smoking makes lungs narrow, people who smoke are more likely to
have a drop in their Peak Expiratory Flow Rate. 2.
Suppose you have two people, one who is active and one who is not. They
have the same resting respiratory rate. What would you expect the
respiratory rate to be after two minutes of exercise?
The individual who is inactive is likely to have a higher respiratory rate than the one who is active.
3. Will there be a difference in flow rates between someone who runs marathons and someone who is a sprinter?
As they are two distinct yet comparable forms of physical activity, it is reasonable to assume that their flow rates will differ.
