This chapter provides a structured approach to analyzing and interpreting the many data points necessary to provide an accurate assessment of normal and abnormal pulmonary function tests. Spirometry provides the foundation of all PFT assessments followed by lung volume and gas transfer interpretation. By the end of this chapter we hope to provide a reproducible and reliable framework for PFT interpretation.
