Exercise Testing, 1965


Tidal volume was monitored with a heated Fleisch pneumotachograph that was mounted downstream of a Hans Rudolph two-way high velocity valve. Exhaled air was collected in plastic and neoprene bags, the volume subsequently measured with precision gas meters.  Gas concentrations were measured with a gas chromatograph.  The bicycle eergometer used friction resistance to maintain and steady workload and the subject pedealed to a metronome. Taken from the “The inhalation of the photochemical smog compound peroxyacetyl nitrate” by Leon E. Smith EdD in AJPH volume 55, no 9, Sept 1965, page 1460.
