BIOS255 Week 7 Lab: #9 Regulation of Pulmonary Ventilation LABORATORY
REPORT
Activity 9: Regulation of Pulmonary Ventilation
Name: Amy Wargo
Instructor: Shahi
Date: 10/15/14
PREDICTIONS
1. Hypercapnia (high arterial carbon dioxide partial pressure) causes minute ventilation
to
increase
2. Hypoxemia (low arterial partial pressure) causes minute ventilation to
increase
MATERIALS AND METHODS
1. Dependent variable: minute ventilation, arterial partial pressure of oxygen and carbon
dioxide and pH
2. Independent variable: inhaled gas mixture
3. Controlled variables: gender, age, BMI, and height; level of physical activity
4. As pCO2 levels were increased, the concentration of a gas in the inhaled air was
decreased in order to maintain the oxygen levels. Name that gas.
Nitrogen
RESULTS
See Table 3: Effect of Hypercapnia on Pulmonary Ventilation
See Graph 1a: Effect of Inhaled Carbon Dioxide on Minute Ventilation
See Graph 1b: Effect of Inhaled Carbon Dioxide on Arterial Carbon Dioxide Partial
Pressure
See Graph 1c: Effect of Inhaled Carbon Dioxide on Arterial Oxygen Partial Pressure
See Graph 1d: Effect of Inhaled Carbon Dioxide on Arterial pH
1. State whether increasing the amount of carbon dioxide in inhaled air increased,
decreased, or did not change minute ventilation from normal.
Increasing the amount of carbon dioxide in inhaled air increased minute ventilation.
