Biological quality control is an alternative to a calibration check. With
biological quality control, you regularly perform tests on healthy subjects.
Overview
The American Thoracic Society (ATS) recommends that calibration be checked
every day. Accordingly, biological quality control must also be performed
every day.
It is practical to choose subjects in your practice or hospital who are available
long-term.
If you suspect a problem with EasyOne Pro/LAB, you can perform a test
promptly on one of the known subjects and see whether the results fall within
the expected range or not.
Detailed description
FEV , FVC, FEV , DLCO, VI, and VA are the spirometry parameters or
1 6
parameters of lung function tests with gas supply used that are for biological
quality control. The software will establish a baseline mean value (precision
range) for each known subject and sensor from trials repeated daily over 20
days.
This baseline will then be used to trend all subsequent biological quality
control tests for this known subject and sensor. Immediate quality feedback
will be provided by the software in accordance with the quality criteria for
biological quality control. This quality feedback alerts you when the collected
parameters deviate too far from the trend.
The biological quality control data will be plotted against time. The biological
quality control reference lines will be mean (precision range), upper limit and
lower limit. The upper and lower limits are +/- 2 standard deviations (SD).
