CareFusion – Vmax Encore


The world leader in Pulmonary function and Cardiopulmonary stress testing technology (CPX / CPET)

Demka Sakti and Carefusion proudly introduces to Indonesia the Vmax Encore, the culmination of Pulmonary Function and Cardiopulmonary stress testing technology and expertise from the people who rewrote the standards for instrumentation.

Vmax Encore offers many features to maximize your laboratory capabilities. The high visibility screen layout and user friendly software makes data collection fast, efficient and easy.Whether you are testing a patient through the use of the simplest or most complex maneuvers, the accuracy and precision of the Vmax Encore system will provide you with unparalleled graphical and numerical data acquisition, display, trending and reporting. Automated post-test QA messaging, utilizing a wide variety of user selectable published standards, assists the practitioner in ensuring the quality and integrity of patient test results.

  • P.100
  • Work of breathing

* Available in the USA for research use.

Non-Effort Dependent Impulse Oscillatory Spirometry

Vmax Encore now offers the option of a fully integrated Impulse Oscillatory Spirometry (IOS) system. IOS may broaden the patient population that can be tested. Pediatric, geriatric and other patients will benefit from the non-effort dependent quiet breathing maneuvers utilized by IOS.With IOS, Vmax Encore can detect more subtle changes as a result of bronchodilator administration than can be detected with traditional spirometric testing maneuvers. The user can differentiate between restrictive and obstructive pulmonary disease. Additionally, IOS allows the operator to perform tests in a smaller physical space than required for a body plethysmograph.


  • Airway resistance
  • Quiet breathing measurements
  • Lung spirometry measurements
  • Greater sensitivity to changes resulting from bronchodilator administration

Consistent CardioPulmonary Exercise Testing

Through the highly efficient Breath-by-Breath, Mixing Chamber, and Dilution modes, Vmax Encore acquires and displays exercise test data in a format that is easy to see and evaluate. Automated or manual selection of AT, automated slope calculation and the ability to overlay and trend are a few of the many features designed to provide maximum ease of use for the user. Vmax Encore is available in single or dual screen configurations and offers the users a high level of configuration flexibility to fit the needs of their testing population. A wide variety of external devices with analog outputs can easily interface with Vmax Encore – automated blood pressure and SPO2 monitors, treadmills and ergometers.


  • Integrated 3- or 12-lead stress EKG
  • Simultaneous Exercise Diffusing Capacity and flow volume loops
  • Portable metabolic testing
  • Elevated oxygen testing
  • Choice of headgear interfaces
  • Track Spirometry during exercise
  • Average and smooth data

  • Physio-cal for QA testing of overall system performance
  • 8-channel analog input box

Accurate Nutritional Assessment

Vmax Encore is designed to provide highly accurate Resting Energy Expenditure (REE) and substrate metabolism test data on patients varying from healthy ambulatory athletes to critically ill ventilator patients in an intensive care unit. Vmax Encore provides the user with a highly flexible graphical display that efficiently and clearly indicates data stability and the patient’s nutritional status.


  • Ventilator interface
  • Spontaneous breathing with canopy
  • Resting Energy Expenditure (REE) and substrate metabolism
  • Simple hook-up to patient circuits on ventilators
  • Easily modify steady-state conditions

Vmax Encore Software with Highly Intuitive Interface
