Description
Test started too early.
Early test start detected.
Detailed criteria:
The time to peak flow (PEFT) is less than 30 ms,
OR flow detected before test was started.
Instruct the patient to wait until the baseline setting is finished and until the
software signals to start the test.
Cough detected.
A cough has been detected.
Instruct the patient to avoid coughing during the measurement.
Gas inspiration time too long.
Long inspiration time detected.
Detailed criteria: Inspiration time is out of range (0.1 – 4.0 seconds).
Instruct the patient to inhale test gas faster.
Breath hold time out of range.
Breath hold time is out of range.
Detailed criteria: Breath-hold time is out of range (8 – 12 seconds).
Instruct the patient to exhale immediately when the corresponding message shows
and when the valve opens.
Calibration result out of range – Check setup.
Calibration result is out of range.
Detailed criteria: The measured volume is out of ±3.5% of the target value.
Check the test setup and repeat the test. If error reappears, contact service.
Try again – Flow criteria not met!
Cal-syringe flow rate too fast or too slow.
Perform the calibration check with the appropriate flow speed.
Inspiratory or expiratory maneuver not detected.
Either only an inspiratory or only an expiratory maneuver detected.
Perform complete inspiratory and expiratory maneuvers and follow the given
instructions.
Check complete gas connection and valve assembly.
Significant difference between calibration and inspiratory CO concentration
detected.
Check complete gas connection and valve assembly, and that test is performed
correctly.
Low inspiratory volume detected.
The inspiratory volume of the DLCO test is <85% of the target value.
Encourage the patient to inhale at least up to the dotted volume line, which indicates
85% of VC .
max
Check complete gas connection and valve assembly.
