Anderson - Alveolar Ventilation, Partial Pressures

Instructor(s): Lisa Anderson

Session Objectives:

1. Draw a diagram of lung volumes labeling Tidal Volume, TLC, RV, FRC and VC. Identify which volumes cannot be measured by spirometry. 
2. Define Deadspace.  Contrast anatomic and physiological deadspace.
3. Calculate minute ventilation, alveolar ventilation and deadspace ventilation.
4. Define partial pressure. Describe the partial pressure gradients that permit the diffusion of oxygen and carbon dioxide across alveolar and tissue membranes.  
5. If shown typical values of oxygen and carbon dioxide for atmospheric, alveolar, arterial and venous partial pressures, describe the significance of changes in those values.
6. Explain the relationship between alveolar ventilation and alveolar PO2 and PCO2. Predict how arterial partial pressure should change with hyperventilation and hypoventilation.
