Vmax™ Encore system Autobox™ cabin Plethysmography
Key features include: • Fast and accurate—all lung volume, resistance and spirometry tests can be
performed in as little as 60 seconds
• Open cabins create less stressful patient environment
• Two cabin sizes—standard and 1,400L wide (largest cabin on the market)
• All tests can be performed in the box, including gas dilution, so “trapped
gas” (difference between body box lung volume and gas dilution lung
volume) can be quantified
• Both VTG and RAW can be obtained via the conventional panting technique or
quiet breathing technique
• Transmural (through the wall) patient breathing allows for compression-free
FVL measurements that accurately determine patient effort
• Equipped with real-time BTPS mass flow sensor that automatically corrects
for changing environmental conditions
The Vmax™ Encore system Autobox™ cabin combines advanced pressure-
compensated flow technology to provide fast and precise measurements of
thoracic gas volumes, including communicating and non-communicating lung
volumes. The system also helps avoid the possibility of underestimating lung
volumes, which is common when testing some obstructed patients with gas
dilution techniques.
Airway resistance/conductance measurements can be referenced to a
specific lung volume, which is useful in determining the patient’s response
to bronchodilator or bronchoprovocation tests. Lung compression can be
measured during the flow volume loop to determine patient effort. Lung
compression is always positively correlated with patient effort.

Fast and accurate—all lung volume, resistance and spirometry texts can be performed in as little as 60 seconds
Two cabin styles available
Two cabin sizes—standard and 1,400L wide (largest cabin on the
market)—to assure comfort for any patient.
The mass flow sensor rotates outside the box in order to perform
non-box tests for maximum ease of use and comfort to the patient.
Lung compression can be
measured during the flow volume
loop to determine patient effort.
Digital filtering (adjustable)
corrects for thermal drift during
quiet breathing RAW.
