A hand-held spirometer, the Respiradyne (R), was evaluated for the measurement of forced expiratory volume in the first second (FEV1), forced vital capacity (FVC) and peak expiratory flow rate (PEFR) by comparing it with a Vitalograph spirometer (V) and a Wright's peak flow meter (W) in 70 subjects (normals and patients).

American Review of Respiratory Disease, 1991
Abstract Pre- and postshift spirometry was obtained on 1,113 blue collar workers employed at 35 work sites judged to have no hazardous occupational respiratory exposures on the basis of inspection visits and environmental sampling. In addition to spirometry, a standardized questionnaire was administered by trained personnel.

A method for determination of %FVC (FEV/FVC%) at forced expiratory flow rate (FEF) of 1 lit./sec. and 0.5 lit/sec from the forced expiratory spirogram is described. This parameter is simpler to determine and is a better expression of end expiratory flow rate than FEF 75%-85%.

The forced end-expiratory flow rate in chloromethyl ether workers.
Journal of occupational medicine. : official publication of the Industrial Medical Association, 1978Spirograms were made in 103 chemical workers, 72 of whom had been exposed for years to chloromethyl ethers to various degrees. The end-expiratory flow rate was below 60% of predicted in one-third of exposed men compared to only 3% of unexposed men. Smoking was a confounding factor.

Forced expiratory volume in 1 second (FEV1) is a reliable and easily measured lung function index, which is nowadays used for early detection of chronic obstructive pulmonary disease. It has also been established recently as an important predictor of all-cause, cardiovascular and cerebrovascular morbidity and mortality in the Western World.

The study group was composed of 2512 healthy children (age range 7-15 years) randomly selected from schools of the Upper Silesian Industrial District. In each child 5 PEF measurements were carried out using the Vitalograph meter. A statistical analysis of the results was carried out.

Effects of upper respiratory infections on the forced expiratory volumes and flow rates.
Indian journal of physiology and pharmacology, 1990The effects of an upper respiratory infection on some commonly measured spirometric indices have been determined in this study. The forcod vital capacity, forced expiratory volume in one second, forced expiratory flow in the middle half of the vital capacity and the peak expiratory flow were significantly lower during the infection.

A 26-year-old male U.S. Navy submariner suffered an arterial gas embolism during pressurized submarine escape training. Routine pretraining medical screening revealed no history of asthma, pneumothorax or recent respiratory infection. Pulmonary function testing and posterioranterior/lateral chest X-ray were normal. He forcefully exhaled at the start of
