Function Testing

Pulmonary function testing was performed in 3 bottlenose dolphins Tursiops truncatus (1 female and 2 males) under managed care during a 2 yr period to assess whether these data provide diagnostic information about respiratory health. Pulmonary radiographs and standard clinical testing were used to evaluate the pulmonary health of each dolphin. The female dolphin (F1) had evidence of chronic pulmonary fibrosis, and 1 male (M2) developed pneumonia during the study. Pulmonary function data were collected from maximal respiratory efforts in water and from spontaneous breaths while beached. From these data, the flow-volume relationship, the flow measured between 25 and 75% of the expired vital capacity (mid forced expiratory flow, FEF25%-75%), and the percent of the vital capacity (VC) at the peak expiratory flow (%VCPEF), were evaluated and compared with the diagnostic assessment. For maximal respiratory manoeuvres in water, there were no differences in FEF25%-75% or %VCPEF, and the flow-volume relationship showed a consistent pattern for F1. Additionally, FEF25%-75% and %VCPEF decreased by 27 and 52%, respectively, and the flow-volume relationship showed clear flow limitations with emerging disease in M2. While spontaneously breathing on land, M2 also showed a 49% decrease in %VCPEF and changes in the flow-volume relationship, indicating flow limitations following the development of pneumonia. Based on these preliminary results, we suggest that pulmonary function testing should be given more attention as a non-invasive and possibly adjunctive diagnostic tool to evaluate lung health of dolphins under managed care and in the wild.

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 impairments, and follow the effects of treatment. Figures illustrate the relationships between lung volume, airway conductance, and airway resistance; the relationship between forced expiratory volume and time (spirogram); the relationship between spirometry and maximum expiratory flow volume; dynamic airway compression; patterns of abnormalities seen on flow-volume curves; lung volumes and capacities; pressure-volume relationships in health and disease; and the clinical assessment of lung function. Tables list the capacities and volumes of gas contained in the lungs during various breathing maneuvers, conditions associated with alterations in diffusing capacity, and recommendations for tests for various clinical scenarios. This review contains 7 highly rendered figures, 3 tables, and 86 references.

Function Testing

Spirometry, also called office-based pulmonary function testing, is a useful tool for diagnosis and classification of lung disease. Here, we outline a simple stepwise approach for interpretation of spirometry results. The first step is to determine the forced expiratory volume in a one second/forced vital capacity (FEV1/FVC) ratio. If airflow is limited, a bronchodilator is administered followed by reassessment. The next step is to determine whether FVC is low; an observed decrease in FVC indicates a restrictive patten. For patients with obstructive disease, inhalation medication is needed. Therefore, this review also describes the most appropriate inhalation device for each patient and the correct use of the device to maximize inhalation therapy benefits.

AbstractObstructing tumours of the upper airways have been demonstrated to alter the flow volume loop of pulmonary function testing. These alterations could be clues to the nature and location of the obstruction. This report describes a case of a pedunculated squamous cell carcinoma arising in the pharynx whose flow volume loop showed a saw tooth pattern which reflected the location and structure of the tumour.

Work-related asthma (WRA) is a very frequent condition in the occupational setting, and refers either to asthma induced (occupational asthma, OA) or worsened (work-exacerbated asthma, WEA) by exposure to allergens (or other sensitizing agents) or to irritant agents at work. Diagnosis of WRA is frequently missed and should take into account clinical features and objective evaluation of lung function. The aim of this overview on pulmonary function testing in the field of WRA is to summarize the different available tests that should be considered in order to accurately diagnose WRA. When WRA is suspected, initial assessment should be carried out with spirometry and bronchodilator responsiveness testing coupled with first-step bronchial provocation testing to assess non-specific bronchial hyper-responsiveness (NSBHR). Further investigations should then refer to specialists with specific functional respiratory tests aiming to consolidate WRA diagnosis and helping to differentiate OA from WEA. Serial peak expiratory flow (PEF) with calculation of the occupation asthma system (OASYS) score as well as serial NSBHR challenge during the working period compared to the off work period are highly informative in the management of WRA. Finally, specific inhalation challenge (SIC) is considered as the reference standard and represents the best way to confirm the specific cause of WRA. Overall, clinicians should be aware that all pulmonary function tests should be standardized in accordance with current guidelines.
