This video will briefly describe the following topics needed to understand the next modules of this course (“Basics Principles of Capnography” and “Interpretation of Capnography Waveforms”):
- The pulmonary anatomy
- Oxygen transport physiology
​- Ventilation perfusion and V/Q mismatch
Understand the physiology of the human respiratory system and its role in the concept known as “gas exchange,” which is dependent on getting gas into and out of the alveoli that are receiving blood, i.e., those alveoli that are both ventilated (getting gas) and perfused (getting blood).

​Optimal gas exchange depends upon matching ventilation and perfusion within the lung; many disease states associated with low oxygen levels or high carbon dioxide levels can be explained by “mismatching” of ventilation and perfusion.
