“…Firstly, SCHILLER and LOWELL [63] found in asthma and emphysema that a slow VC is larger than a fast one. Secondly, FRANKLIN et al [64] observed this apparent paradox: in patients with obstructive disease a maximal effort sometimes yields a slightly slower expiratory rate than a submaximal effort. In Europe, SADOUL [65] repeatedly emphasized that forced expiratory manoeuvres should be performed "en souplesse" (flexible).…”

“…In Europe, SADOUL [65] repeatedly emphasized that forced expiratory manoeuvres should be performed "en souplesse" (flexible). FRANKLIN et al [64] also pointed out that, in asthma, physical findings are often misleading and that many patients are poor judges of their condition, and they recommended the spirogram as a useful objective method. As SADOUL and GUILLET [36] before them, they confirmed the superiority of tracings over timers, so that malingering could be easily detected.…”

The birth and development of the forced expiratory manoeuvre: a tribute to Robert Tiffeneau (1910-1961)

The forced expiratory manoeuvre was first described by Tiffeneau and Pinelli working in Paris (France), in December 1947, who proposed measurement of the "pulmonary capacity usable on exercise" (capacite pulmonaire utilisable a l'effort) (CPUE), the maximal volume expelled in one second after a deep inspiration. It was intended to replace the measurement of the maximum breathing capacity, a difficult and tiring manoeuvre. A similar approach was later followed in the USA by Gaensler, who proposed the "timed vital capacity" in 1951. The name CPUE was changed to "volume expiratoire maximum seconde" (VEMS) by a group of European experts, who met in Paris on February 13, 1954, whereas the expression "forced expiratory volume" was adopted by the British Thoracic Society in 1957. Despite numerous attempts to examine the forced expiration in a different manner, the VEMS and/or forced expiratory volume in one second (FEV1) remain, after 50 yrs the main variables used daily by the respiratory physician. Although primarily a pharmacologist, Robert Tiffeneau (1910-1961) undoubtedly deserves to figure among the pioneers of respiratory medicine.

“…Although John Hutchinson introduced vital capacity measurements in the 1840s (7), time-dependent FEV was not introduced until 1947 (8). Bronchodilator responsiveness in FEV 1 emerged as a diagnostic criterion for asthma in the 1950s, although the sensitivity and specificity of this test were never formally addressed (9,10).…”

“…I won't be able to publish the data, but I've been involved in a project where initially only 60% of the tests done at 300 sites across the United States (primarily in occupational and primary care settings) met the ATS goals for quality. 1 A legal contract then stipulated payment only for spirometry tests that met ATS quality goals. Very quickly, the spirometry quality from the same providers increased 96%, meeting the quality goals, and has persisted in the high 90s ever since.…”

Quality Assurance of the Pulmonary Function Technologist

The skill and work habits of the pulmonary function technologist are central to the quality of patient testing. Pulmonary function technologists should be chosen carefully. The pulmonary function technologists must be intelligent, conscientious, and possess critical thinking skills. Studies are needed to better identify which kinds of personality traits correlate with superior job performance and whether or not such traits can be reliably identified by standardized testing. Monitoring of technologist performance and technologist feedback improves the quality of testing but is utilized by only a minority of clinical laboratories. Pulmonary function laboratory accreditation is urgently needed to protect the public from potential misdiagnosis and inappropriate treatment due to spurious data.
