Intelligent management of pulmonary disease requires a fundamental understanding of the complex interrelationships between multiple elements that interact to maintain homeostasis in the respiratory system. This chapter discusses the physiologic basis for pulmonary function testing and the use of these tests to diagnose disease, quantitate functional ...

Evaluation of computed tomography in the diagnosis of ultrasound-proven diaphragm dysfunction
Introduction Computed tomography (CT) is routinely employed on the evaluation of dyspnea, yet limited data exist on its assessment of diaphragmatic muscle.

Homeostatic mechanisms and the normal sizable cardiopulmonary reserve can combine to adjust ventilation and perfusion so that arterial gas tensions remain within normal physiologic limits, despite the presence of widespread lung disease and severe mechanical impairment of the respiratory apparatus.

Combined pulmonary fibrosis and emphysema (CPFE) has been increasingly recognized over the past 10−15 years as a clinical entity characterized by rather severe imaging and gas exchange abnormalities, but often only mild impairment in spirometric ...

Occupational health surveillance: Pulmonary function testing in emergency responders
Emergency responders may be exposed to a variety of fumes, gases, and particulates during the course of their job that can affect pulmonary function (PF) and require the use of respiratory protection.

Using Operational Analysis to Improve Access to Pulmonary Function Testing
Background. Timely pulmonary function testing is crucial to improving diagnosis and treatment of pulmonary diseases. Perceptions of poor access at an academic pulmonary function laboratory prompted analysis of system demand and capacity to identify ...

Swimming-induced changes in pulmonary function: special observations for clinical testing
Background A special improvement in pulmonary function is found in swimmers. In clinical testing the airway reactivity is observed at certain exercise intensity and target ventilation. However, in highly trained swimmers exercising in water the reactions

Abstract Pulmonary function tests (PFTs) include the measurement of velocity and volume of expiratory flow (spirometry), static volumes (lung volumes), diffusion of gases across the alveolar-capillary membrane (diffusion capacity), and respiratory muscle strength.
