II. Introduction – CareFusion USA
The MicroDL spirometer is a compact, battery operated, and fully
portable data recording spirometer designed to collect spirometry
data, expiratory Flow/Volume and Volume/Time curves, and
symptom scores.
The MicroDL can be configured for use with a single patient for
detailed monitoring over a period or for collecting spirometry data
from a number of patients.
Alternatively, the data may be uploaded to a PC running the fully
featured Spirometry PC Software (SPCS). Once uploaded, the data
may be viewed individually or as a trend graph with symptom scores
(in single patient mode) and the Flow/Volume loop of any individual
point examined. SPCS may also be used to perform live spirometry
tests and show the expiratory Flow/Volume loop, Volume/Time curve
and child incentive displays.
In single patient mode the user can perform a spirometry test and
enter symptom scores or event markers. After each spirometry
manoeuvre the results are displayed together with a ‘traffic light’
indication of their performance as an aid to asthma management.
The levels that activate the red, amber and green lights, as a
percentage of the predicted value, can be selected when the unit is
configured. Alternatively, the activation may be based on the
patient’s personal best values when the unit is configured using the
SPCS software.
In multiple patient mode spirometry results can be collected from up
to 200 patients. In this mode the ‘traffic light’ activation is based
upon the patient’s predicted values and symptom scores are not
used.
