Viasys Vmax Encore Repair

The Viasys Vmax Encore was released in 2005 as a system that could be used as a PFT system or a metabolic cart system in four different configurations. The system could come as the Vmax Encore 20 Pulmonary Spirometry Instrument, Vmax Encore 22 Pulmonary Function Analysis Instrument, Vmax Encore 29 Cardiopulmonary Exercise Testing Instrument, or Vmax Encore 229 Pulmonary Function/Cardiopulmonary Exercise Testing Instrument.

The first two listed use the system to test the respiratory system by testing breathing while the latter two function as metabolic cart systems that deal in exercise and calorimetry.

The original manufacturer of the device, Viasys, was bought out by Vyaire, and the new manufacturer renamed the device the Vmax Encore.

The module by itself weighs 31 lbs, and consists of a computer or notebook, the program software, printer, and the Encore module containing different components based on configuration. Additional components may exist depending on configuration and extra features added. The device may come on a cart or table depending on where it was purchased. It also comes with one to two monitors, a keyboard, and mouse.
