Respiratory Acidosis and Alkalosis
Activity 1: Normal Breathing
1. At 20 seconds, pH = 7.41
2. At 40 seconds, pH = 7.38
3. At 60 seconds, pH = 7.39
4. Did the pH level of the blood change at all during normal breathing? If so, how? Yes it did. It went down and then back up a little bit. 5. Was the pH level always within the “normal” range for the human body? yes 6. Did the PCO2 level change during the course of normal breathing? If so, how? No it did not

Activity 2a: Hyperventilation – Run 1
7. At 20 seconds, pH = 7.49
8. At 40 seconds, pH = 7.57
9. At 60 seconds, pH = 7.69
10. Maximum pH =7.69
11. Did the pH level of the blood change at all during this run? If so, how? Yes it elevated 12. Was the pH level always within the “normal” range for the human body? If not, when was the pH value outside of the normal range, and what acid/base imbalance did this pH value indicate? No it was not. Normal pH = 7.35-7.45. I was out of range by 20 seconds. 13. Did the PCO2 level change during the course of this run? If so, how? No the maximum PCO2 did not change, how ever the minimum did go down. 14. If you observed an acid/base imbalance during this run, how would you expect to renal system to compensate for this condition? 15. How did the hyperventilation trace differ from the trace for the normal breathing? Did the tidal volumes change? 16. What might cause a person to hyperventilate?

Activity 2b: Hyperventilation – Run 2
17. What happened to the trace after the 20-second mark when you stopped the hyperventilation? Did the breathing return to normal immediately? Explain your observation.

Activity 3: Rebreathing
18. At 20 seconds, pH =
19. At 40 seconds, pH =
20. At 60 seconds, pH =
21. Did the pH level of the blood change at all during this run? If so, how? 22. Was the pH level always within the “normal” range for the human body? If not, when was the pH value outside of the normal range, and what...
