Respiratory Acidosis and Alkalosis
Activity 1: Normal Breathing
1. At 20 seconds, pH = 7.38
At 40 seconds, pH = 7.38
At 60 seconds, pH = 7.38
2. Did the pH level of the blood change at all during normal breathing? If so, how? No, it remained constant at 7.38
3. Was the pH level always within the “normal” range for the human body?
Yes, the pH level remained normal within 7.35 and 7.45
4. Did the PCO2 level change during the course of normal breathing? If so, how?
No, it remained constant at 40
Activity 2a: Hyperventilation – Run 1
1. At 20 seconds, pH = 7.41
At 40 seconds, pH = 7.52
At 60 seconds, pH = 7.67
2. Maximum pH = 7.68
3. Did the pH level of the blood change at all during this run? If so, how?
Yes, it increased and decreased in order to maintain balance.
4. 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?
The pH balance was not always within the normal range it became higher, therefore it was considered to be in a state of respiratory alkalosis.
5. Did the PCO2 level change during the curse of this run? If so, how?
Yes, it changed from 40 to 19.7.
6. If you observed an acid/base imbalance during this run, how would you expect to renal system to compensate for this condition?
The renal system would compensate by controlling the output of acids, basis or carbon dioxide from the body within urine.
7. How did the hyperventilation trace differ from the trace for the normal breathing? Did the tidal volumes change?
The
