[Functional approach to asthma (author's transl)]. 1979

F Ruff, and M Bernadou

The different pulmonary function tests which enable the diagnosis of asthma and its functional criterium, reversible bronchial obstruction, are reviewed. It is our opinion that in epidemiology where the diagnosis should be made "on the spot" in a simple, rapid and non-aggressive manner, the most appropriate tests are the following: the FEV1 or other forced expiration parameters, to which could be added the measurements of closing volume, the slope of phase III, and/or flow-volume curves using two gas mixtures. The modifiers of bronchomotricity could confirm the reversible nature of the bronchial obstruction.

UI	MeSH Term	Description	Entries
D008170	Lung Compliance	The capability of the LUNGS to distend under pressure as measured by pulmonary volume change per unit pressure change. While not a complete description of the pressure-volume properties of the lung, it is nevertheless useful in practice as a measure of the comparative stiffness of the lung. (From Best & Taylor's Physiological Basis of Medical Practice, 12th ed, p562)	Compliance, Lung,Compliances, Lung,Lung Compliances
D008449	Maximal Expiratory Flow-Volume Curves	Curves depicting MAXIMAL EXPIRATORY FLOW RATE, in liters/second, versus lung inflation, in liters or percentage of lung capacity, during a FORCED VITAL CAPACITY determination. Common abbreviation is MEFV.	Maximal Expiratory Flow Volume Curves
D012129	Respiratory Function Tests	Measurement of the various processes involved in the act of respiration: inspiration, expiration, oxygen and carbon dioxide exchange, lung volume and compliance, etc.	Lung Function Tests,Pulmonary Function Tests,Function Test, Pulmonary,Function Tests, Pulmonary,Pulmonary Function Test,Test, Pulmonary Function,Tests, Pulmonary Function,Function Test, Lung,Function Test, Respiratory,Function Tests, Lung,Function Tests, Respiratory,Lung Function Test,Respiratory Function Test,Test, Lung Function,Test, Respiratory Function,Tests, Lung Function,Tests, Respiratory Function
D003011	Closing Volume	The lung volume at which the dependent lung zones cease to ventilate presumably as a result of airway closure.	Closing Volumes,Volume, Closing,Volumes, Closing

D000403	Airway Resistance	Physiologically, the opposition to flow of air caused by the forces of friction. As a part of pulmonary function testing, it is the ratio of driving pressure to the rate of air flow.	Airway Resistances,Resistance, Airway,Resistances, Airway
D001249	Asthma	A form of bronchial disorder with three distinct components: airway hyper-responsiveness (RESPIRATORY HYPERSENSITIVITY), airway INFLAMMATION, and intermittent AIRWAY OBSTRUCTION. It is characterized by spasmodic contraction of airway smooth muscle, WHEEZING, and dyspnea (DYSPNEA, PAROXYSMAL).	Asthma, Bronchial,Bronchial Asthma,Asthmas
D013147	Spirometry	Measurement of volume of air inhaled or exhaled by the lung.	Spirometries
