Performed spirometry, helium dilution lung volumes and single-breath DLCO. Could be upgraded to include closing volumes and N2 washout kung volumes. Used a wedge spirometer. Came equipped with a top-of-the line IBM PC XT with dual 5-1/4″ floppy disk drives (!).

Fukuda Sangyo FUDAC-60 Pulmonary Testing System, 1984
It came with a 10″ color CRT in 6 different models. The basic unit was capable of performing spirometry, helium dilution lung volumes and single-breath DLCO. N2 washout lung volumes, closing volumes, steady-state DLCO and Viso-V (heliox spirometry) were options.

Gould 5000 IV Pulmonary Testing System, 1983
The Gould 5000 IV was capable of performing spirometry, single-breath DLCO, closing volumes and either helium dilution or nitrogen washout lung volumes. It came with a “large 9″ CRT for real-time graphics”. Photo from a sales brochure courtesy of James Sullivan, BA, RPFT, Supervisor, Pulmonary Laboratories, Memorial Sloan Kettering Cancer Center
N2 Washout Lung Volume testing, 1974
Hewlett Packard 47804S PFT System – 1979
State of the art for 1979. Built around a Fleisch pneumotachograph and included an HP desktop computer (with 24K of memory and a tape drive!). It was capable of performing spirometry, DLCO and N2 washout tests. It was only manufactured for a couple of years and was discontinued likely because very few units were sold. It was quite expensive for the time (totally equipped it was $53,175 in 1979 dollars). From “Automated pulmonary function measurements” by Maurice R. Blais and John L. Fanton, Hewlett-Packard Journal, September 1979, page 20.
