PhysioEx Lab Report Exercise 10: Acid-Base Balance Activity 1: Hyperventilation Name: Krystal Cookson Date: 4 June 2020 Session ID: session-21ed7eff-6922-bbbc-0793-a4e18a50b24c

Pre-lab Quiz Results You scored 100% by answering 4 out of 4 questions correctly. 1 The fastest compensatory mechanism for maintaining pH homeostasis in the human body is You correctly answered: the chemical buffering system. 2 An increase in hydrogen ion concentration would You correctly answered: decrease pH. 3 The amount of carbon dioxide in the blood is measured in You correctly answered: mm Hg. 4 The reaction of water and carbon dioxide is catalyzed by You correctly answered: carbonic anhydrase.

Experiment Results Predict Question 1 Predict Question: What do you think will happen to the pH and P

CO2levels

with

hyperventilation? Your answer: pH and P CO2 will decrease. Stop & Think Questions 1 Were the pH and P CO2 in the normal range? You correctly answered: Both pH and P CO2 were in the normal range. 2 What was the effect of returning to normal breathing after hyperventilation? You correctly answered: The breathing stopped temporarily to retain carbon dioxide. Experiment Data https://media.pearsoncmg.com/bc/bc 0media ap/physioex/10/ex10/act1/

Post-lab Quiz Results You scored 100% by answering 4 out of 4 questions correctly. 1 Hyperventilation results in You correctly answered: respiratory alkalosis. 2 With hyperventilation, the higher peaks on the tracing indicate You correctly answered: a larger volume of air. 3 Which of the following is not a potential cause of respiratory alkalosis? You correctly answered: emphysema. 4 The kidneys can compensate for respiratory alkalosis by You correctly answered: retaining H + and excreting bicarbonate ion.

Review Sheet Results 1 Describe the normal ranges for pH and carbon dioxide in the blood. Your answer: pH: 7.35-7.45 pCO2: 34-45 mmHG. 2 Describe what happened to the pH and the carbon dioxide level with hyperventilation. How well did the results compare with your prediction?

pH and Pco2 decreased with hyperventilation. 3 Explain how returning to normal breathing after hyperventilation differed from hyperventilation without returning to normal breathing. Your answer: Returning to normal breathing from hyperventilation differed due to the breathing pattern changed to replenish the CO2. 4 Describe some possible causes of respiratory alkalosis. Your answer: Traveling to high altitudes, hyperventilation due to fever, panic attacks and anxiety.
