Скачать или смотреть The Lungs Part 4 - Obstructive Vs Restrictive Lung Diseases. Resistance & Compliance. FVC & FEV1

This lecture starts by discussing the equation for airflow and defining airway resistance and lung compliance. It then Discusses the factors which influence lung compliance and airway resistance. Next it discusses what obstructive and restrictive lung diseases are. Finally, it defines spirometry and explains how forced vital capacity and forced expiratory volume over one second can be used to diagnose obstructive and restrictive lung diseases.
