PFT System, Sensormedics VMax229, circa 2000, Front
The VMax229 could be used as a metabolic measurement cart (VO2, VCO2, Ve etc) or as a standard pulmonary function testing system (spirometry, N2 washout lung volumes and DLCO). From http://www.ebay.com/itm/SENSORMEDICS-VMAX-229-SPIROMETER-PULMONARY-RESPIRATORY-ANALYZER-769200-101-/290931490837

“Measurements were made as follows: after exhaling to residual volume, the subject went on the mouthpiece and rapidly inhaled a measured volume of the gas mixture from bag A. This breath was held for a measured time after which is was exhaled rapidly. The first liter of exhalate was allowed to clear the dead space, after which tap A was turned 90 degrees counter clockwise and an alveolar sample of a bout a liter was collected in bag B. t was not convenient to clamp this wide-mouthed sampling bag and remove it; therefore, the sample was aspirated into another removable bag C, in which it was sealed and set aside for later analysis.”
