A blue and black cuboid instrument. At the centre of the top face of the instrument there is a slot for a respirograph chart. Above this are two cavities for storing disposable recorder pens. A green test button and a white switch are located below the slot.
Towards the bottom of the front face of the instrument, there is a circular mounting point for a breathing tube. This instrument does not come with a breathing tube. On either side is a clip for opening the instrument. A power cord is attached to the back side of the instrument.
This artifact comes with the following consumables, tools, and documents:
– One package of 6 red disposable recording pens manufactured by WEC inc.
– One package of 4 black disposable recording pens manufactured by WEC inc.
– One package of 4 black disposable recording pens manufactured by Vacumetrics Inc.
– One package containing 6 disposable nose plugs and four loose disposable pen covers.
– One small package containing one red and two black disposable recording pens unknown manufacture. These appear to be of a different format than those used by this machine.

Spirometry is a test to measure vital capacity in order to diagnose airway obstruction. A spirometer is an office instrument to provide a measurement of vital lung capacity.
This volume displacement spirometer provides a recording of a time/ volume curve of a patient’s exhalation.
Very good: There are slight abrasions on the finish of the top surface of the main instrument. The instrument no longer has a breathing tube.

Date of Manufacture: c. 1982
This instrument was used in the office of Dr. Stan Epstein. It was acquired along with a collection of medical artifacts from his home on February 19, 2019.
Additional Information and References:
This instrument represents an earlier generation of spirometers that measure vital capacity using a time/ volume curve. Later instruments use a flow/ volume measurement.
