Introduction
The Micro Direct spiroLung Monitor was specifically
designed for situations where low cost, easy to use, accurate
spirometry with a report is required.
The spiroLung Monitor accurately measures, displays and
stores the actual FEV1, FEV6 , FEV1/FEV6, FEF25-75 and the percent
of Personal Best FEV1. The personal best FEV1can be set by the
clinician with future patient efforts compared to their personal best.
The three color action zones are preset but can be customized by
the clinician.
With the Spirometry Reports Software, the results can be
uploaded to a computer to generate a report that can be sent to
the physician.

will return to the test screen.
Note: to de-activate zones, set the FEV1 reference value to 0.00.

management plans. The zone percentages are factory set to 2
boundaries, 95% & 90%, i.e. 3 Zones (95-100%, 90-95%, 0-90%).
For 4 zones the middle boundary is set last. The color systems for
each zone type are as follows:
