Mechanics of Ventilation and the Effect of IPPV on the Lungs

About this activity

This session continues to look at respiratory mechanics. Lung compliance and the role of surfactant are discussed as are the factors determining whether airflow is laminar or turbulent. Respiratory function tests will also be explained. Objectives By the end of this session you will be able to: • Discuss the concept of compliance • Explain Laplace’s law and understand the role of surfactant • Recognize the factors affecting airflow through the lung • Interpret the results of lung function tests in obstructive and restrictive disease
