Introduction - Micro Direct Micro I Operating Manual

Introduction

The Micro I is a compact, rechargeable battery operated and fully
portable diagnostic spirometer. It is accurate to the requirements
of the ATS/ERS TASK FORCE: STANDARDIZATION OF LUNG
FUNCTION TESTING 2005. Its ergonomic and user-friendly
design allows diagnostic spirometry measurements, including
predicted values and automatic interpretation, to be made quickly
and simply.
The Micro I features include:
✓ Measures FEV
PEF, FEF
✓ Fully configurable using software supplied
✓ ECCS, Asian, NHANES III Kainu (2016) Finnish, Quanjer
GLI (2012) or Quanjer GLI (2012) + ECCS predicted
values
✓ Variation from norm as a percentage or Z-score
✓ NLHEP, NICE or the ATS/ERS interpretation
✓ Spirometry maneuver quality checks
✓ Post bronchodilator comparison
✓ NLHEP compliant mode
✓ Upload of the last patient tested for report generation
either to be printed directly or saved as a PDF document
and printed or stored in the patient's electronic medical
records.
The spirometer uses a digital volume transducer, an extremely
stable form of volume transducer, which measures expired air
directly at B.T.P.S. (Body Temperature and Pressure with
Saturated water vapor) thus avoiding the inaccuracies of
temperature corrections. This transducer is insensitive to the
effects of condensation and temperature and avoids the need for
individual calibration prior to performing a test.
