Vmax Encore metabolic cart

Comprehensive cardiopulmonary stress testing and indirect calorimetry testing in one metabolic cart

Cardiopulmonary stress testing and indirect calorimetry testing in one metabolic cart. Use as standalone device or combine with a Vmax PFT system and save money.

  • Provides wide range of application for CardioPulmonary Exercise Testing (CPET) of sick patients and elite athletes, children, and adults, even patients requiring supplemental Oxygen.
  • Also accurately assesses indirect calorimetry (metabolic rate) on spontaneous breathing and ventilator-dependent infants, children, and adults.
  • Both Mixing Chamber and Breath-by-Breath (BxB) technology is available in the same instrument.
  • Multiple patient interface options, including mask, mouthpiece, canopy and dilution mask.
  • Vmax Encore software provides Easy Trending (table form and graphically) of previous and current tests which is of great use for evaluating rehab patients.
  • Automated or manual selection of anaerobic threshold (AT), automated slope calculation as well as baseline and Peak Values detection improves and shortens report processing time.
  • EZ-view graphic display with colour coding (Green, Yellow, Red) lets you keep focused on your patient.
  • Interpretative and narrative statements with short cut keys helps physicians accurately and quickly read CPET and nutritional tests.
  • Integrated Spirometry software meets all American Thoracic Society recommendations. Tidal breathing flow volume loops during exercise testing is extraordinarily useful for the detection of exercise airflow limitation.
  • Our metabolic carts can be configured as a combination metabolic/complete PFT system to save you significant expense, both up front and in warranty costs.
  • Vmax can perform Exercise Diffusing Capacity measurements to so you can examine the relationship between pulmonary blood flow and gas exchange.
  • Simple limb lead or complex 12 lead ECG, bicycle ergometers, treadmills, pulse oximeter, and other devices can interface and share information with Vmax.
  • Export data to Excel or SQL.
  • SentryConnect with HL7 and ADT communicates bidirectionally with your Hospital Information System.
