An algorithmic approach to pulmonary function tests for cardiologists

Abstract

Abstract Pulmonary function tests (PFTs) and chest roentgenogram form a gateway to more advanced tests during diagnostic workup of a suspected respiratory disorder. Since the heart and lungs form an integrated physiological system, cardiovascular and pulmonary disorders coexist frequently. For this reason, and several other reasons, cardiologists should have an understanding of pulmonary function testing to manage their patients effectively. Interpreting PFTs may seem complex for a nonpulmonologist, but a systematic approach makes it really a simple process to facilitate a correct cardiopulmonary diagnosis in many instances.
