New! Memory Volume Indicator (MVI) Mode Provides Verification of Recorded Data for Oxygen Qualification Studies

The Model 3150 with MVI mode provides a graphic display of the amount of recorded data in the Model 3150 in hours and minutes. In the MVI mode, the Model 3150 provides assurance to Independent Diagnostic Testing Facilities (IDTFs) and Home Care companies that sufficient data has been recorded during oxygen verification testing; preventing unnecessary trips for repeat recordings, reducing costs, and improving overall efficiencies.


In MVI mode, the Model 3150 LCD displays only the hours and minutes of recorded data stored in its memory. The MVI mode can only be enabled by the IDTF. An update in Nonin’s nVISION® software is available to allow enabling the MVI mode for previously produced Model 3150s.
