Exercise 10 Acid Base Balance Essay

Register to read the introduction… At 20 seconds, pH = 7.35 2. At 40 seconds, pH = 7.29 3. At 60 seconds, pH = 7.24 4. Did the pH level of the blood change at all during this run? If so, how? Yes, the pH level of the blood decreased. 5. 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, acidosis occurred at 40 seconds when the pH dropped out of “normal” range to 7.29. 6. Did the PCO2 level change during the course of this run? If so, how? Yes, the Pco2 level elevated. 7. If you observed an acid/base imbalance during this run, how would you expect the renal system to compensate for this condition? Increasing HCO3-, excreting more H+ to balance the pH of the blood. 8. How did the rebreathing trace differ from the trace for normal breathing? Did the tidal volumes change? Rebreathing trace had a larger gap between the varying high and low points. Normal breathing it was approximately 2.5-3 liters, whereas rebreathing was approximately 2.-3.5 liters. 9. Give examples of respiratory problems that would result in pH and PCO2 patterns similar to what you observed during …show more content…

Activity 4: Renal Response to Normal Acid/Base Balance

1. At normal PCO2 and pH levels, what level of H+ was present in the urine? Normal. 2. What level of [HCO3-] was present in the urine? Normal. 3. Why does the blood pH value change as PCO2 changes? An increase in carbon dioxide in body fluids increases the H+, which lowers the pH. 4. How does the blood pH value change as Pco2 changes? As Pco2 elevates the blood pH
