Assessing Structure–Function Relations in Mice Using the Forced Oscillation Technique and Quantitative Histology

Part of the Methods in Molecular Biology book series (MIMB, volume 1639)

Abstract

The structure and function of the lung gradually becomes compromised during the progression of emphysema. In this chapter, we first describe how to assess and evaluate lung function using the forced oscillation technique. Next, we provide details on how to use the Flexivent system to measure respiratory mechanical parameters in mice. We also describe the outlines of how to set up a homemade forced oscillatory system and use it to measure respiratory mechanics. To characterize the structure from standard histological images, we describe a method that is highly sensitive to early emphysema. Correlating structural information such as equivalent alveolar diameter and its variance with respiratory elastance or compliance, provides structure–function relationships that can subsequently reveal novel mechanisms of emphysema progression or be used to track the effectiveness of treatment.
