The role of respiratory function testing

Lung Cancer, 1993
Many patients with bronchogenic carcinoma have co-existent generalized lung disease and must be carefully assessed prior to having surgery or receiving radical radiotherapy, as these treatment modalities may result in significant further functional impairment.

Diseases of the Respiratory System Interpretations of Tests of Function

Annual Review of Medicine, 1955
The lungs are perfectly designed to fulfill their function of ensuring full oxygenation of the blood and they achieve this by possession of the follow­ ing properties: (a) The distensibility and elasticity of the lungs enables a large volume of gas to be moved in and out of the alveoli at a rapid rate and with minimal effort.

Practical value and limitations of respiratory functions tests

Journal of Allergy, 1952
Abstract 1.1. Ventilatory function tests under office conditions provide useful information on functional and structural changes of the patient with bronchial asthma. Of these, vital capacity, expressed as a function of time and maximum voluntary ventilating capacity are dynamic measurements which are superior to the static measurement of vital ...

The contribution of respiratory function tests to clinical diagnosis

European Respiratory Journal, 1993
The purpose of this study was to investigate the amount of diagnostic information contained in a set of routine lung function studies and to attempt to determine which tests could be omitted without significant loss of discrimination. Cluster analysis was performed on a set of physiological and questionnaire data, collected prospectively in 1,542 male ...

The Relationship of Respiratory Function Tests to Respiratory Symptoms and Smoking in Older People

Respiration, 1972
The FEV1•0% was calculated from FEV1 0 and FVC measured in a random sample of older people in Edinburgh. The proportion of persons with FEV1 0%

Respiratory Function Tests in Pulmonary Rehabilitation

1993
Respiratory rehabilitation programs are widely employed in the management of patients with respiratory diseases. Nevertheless only few prospective, randomized or controlled studies have been performed on these programs and their clinical efficacy is still debated.

Interpretation of Preoperative Cardio-Respiratory Function Tests

Surgery (Oxford), 2003
Abstract Preoperative cardio-respiratory tests aim to identify patients with increased perioperative risk, enabling clinicians to assign optimal preoperative treatment, anaesthetic management and intraoperative monitoring techniques, and assess the need for postoperative ‘high dependency’ or intensive care.

RESPIRATORY FUNCTION TESTS IN ABORIGINAL CHILDREN ON MORNINGTON ISLAND

Medical Journal of Australia, 1980
Lung function tests using a dry spirometer were performed on school-age Aboriginal children living on Mornington Island in the Gulf of Carpentaria. Although the mean values were below Caucasian standards, they were within the appropriate normal range. There is no evidence in this study to suggest that there is a high prevalence of residual lung damage.

Variations in function and design: Testing symmorphosis in the respiratory system

Respiration Physiology, 1992
We explore the question of whether and to what extent the large variation in energy requirements observed among mammals is related to variations in the design of the respiratory system, from the lung to the mitochondria in muscle cells. Resting metabolic rate is determined by body size (allometric variation).

Clinical application of respiratory function tests

1984
Before requesting or performing tests of respiratory function it is worth while to pause and consider the question ‘What information is required?’, since the answer will determine which tests are appropriate. Clearly this will depend on the clinical context: possible answers would include assessment of the severity of airflow obstruction, screening for
