1890in Gould New Med. Dict. 1934Publ. Mod. Lang. Assoc. Amer. XLIX. 1168 The air pressure and vibrations taken back of the point of contact with the spirograph. 1977Bull. Exper. Biol. & Med. LXIV. 1662 The investigation is stopped when changes in the helium concentration in the spirograph decrease to a certain small value.
Hence ˈspirogram, the tracing produced by a spirograph; spirographic a., pertaining to or observed by means of a spirograph; spiroˈgraphically adv.; spiˈrography, the study of respiration by means of a spirograph.

Gay Bronchial Asthma i. 7 (caption) Spirographic tracings of Hofbauer. 1956Hinshaw & Garland Dis. of Chest vi. 89 Tracings of respiration, sometimes called spirograms, are readily made by means of a calibrated spirometer equipped with a writing device. 1959Presse Médicale No. 47. Suppl. 2/1 Having studied clinically and spirographically a population of 232 patients, authors make first a distinction between three groups according to the intensity of dyspnea. Ibid., Spirography allows effectively to make a distinction between three groups of patients. 1977Lancet 22 Jan. 156/1 (caption) Spirogram of habitual hyperventilator showing irregular amplitude and frequency of respiration and sighing tendency. Ibid. 26 Mar. 709/1 Their diagnosis of hyperventilation is based on..a spirographic pattern for which criteria of abnormality are lacking. 1977Bull. Exper. Biol. & Med. LXXXIII. 3 On the basis of indices obtained by the motion-picture spirography method, a definite idea can thus be obtained of the functional state of the apparatus for controlling respiration under different conditions. |
