No less important is also understanding at least the basic physiological principles of breathing in health and disease.
This knowledge is of critical importance especially for a bronchoscopist to ensure safety of the procedure and for interpreting dynamic abnormalities within the airways during a bronchoscopy. Airway patency, stability, and variability of airway obstruction play an important role in many respiratory diseases, such as congenital defects, asthma, and some inflammatory conditions.
Reducing the airway lumen when inserting a bronchoscope may lead to increased airway resistance and altered air flow. This may cause some misinterpretation of bronchoscopic findings.
Understanding lung physiology and the possible changes in breathing during bronchoscopy is also very important for conducting safe anesthesia. This chapter provides a review of the basic physiological principles related to the airways and the respiratory tract with special focus on interference of bronchoscopy and breathing.
