Respiratory System Physiology

This chapter will cover basic concepts of lung physiology in health and disease. The concepts we present are aimed toward the anesthesiologist, focusing on the topic to a degree of detail to encourage recall and practical knowledge. Understanding the respiratory system physiology is a key element in the work of the anesthesiologist. Not only does the anesthesiologist rely on the respiratory system to ensure appropriate gas exchangeGas exchange, but it is the means for drug delivery and allows us to obtain information about the body status with simple measurements.
