5 Questions
What does Fick’s law of diffusion state?
Gas diffuses through a sheet of tissue at a rate directly proportional to tissue area, diffusion constant, and pressure differential of gas on each side of the membrane
What is the minute ventilation (Ve) equation?
Ve = breathing rate x tidal volume
What does the term 'anatomic dead space' refer to?
Air in each breath that doesn’t enter alveoli and therefore doesn’t participate in gas exchange
According to Henry’s law, what governs gas diffusion into a fluid?
Pressure differential between gas above fluid and gas dissolved in fluid
What is one function of OxyHb (Oxyhemoglobin)?
Carries 65-70 times more O2 than dissolved in plasma
Test your knowledge of key concepts in pulmonary physiology, including Fick’s law of diffusion, minute ventilation, alveolar ventilation, and anatomic dead space.
