*ERS Group 9.1, ATS/APCCSDD Task Force

Easy to use, the MiniBox+™ pulmonary function test device provides accurate and repeatable, fully automatic measurements of Total Lung Capacity (TLC) and Residual Volume (RV), as well as single breath CO Diffusion (DLCO). With as little as 60 seconds of tidal breathing required for Lung Volume Measurements, this gasless, cabinless system provides maximum patient comfort.

In a recent multi-center study published in CHEST, MiniBox+ lung volumes were shown to be equivalent to body plethysmography (“body box”).


Fully Automatic Lung Volume Measurements and DLCO. Testing can be performed by anyone on your medical office staff. All results automatically generated.


Clinically validated in over 500 patients at 8 medical centers, the pulmonary function test results are highly accurate and repeatable.


ROI achievable within months,
with testing of only
2 to 5 patients daily.
