Note: If an older exam is being reviewed and it was conducted with SDM software < 1.12 or
unit firmware < V3.02, the exam will be presented with quality messages from ATS/ERS
2005 guidelines instead of ATS/ERS 2019, and could be one of the following messages:
Slow Start:
The patient appeared to have paused slightly at the beginning of the
manoeuvre. He/she should blast air out as hard as possible from the
very beginning of test
Abrupt End:
The patient appeared to stop blowing suddenly. The patient should
continue to squeeze every last bit of air out of their lungs at the end of
exhalation. A good guideline is that they should not stop before they have
exhaled for 6 seconds at least (the graph border turns green after 6
seconds to indicate this time has elapsed)
Possible Cough:
A possible cough has been detected.
Good Blow:
The blow is of good quality
The ACCEPTANCE CRITERIA messages for the current exam are shown below the Results

(Base, Post1, Post2) and depend upon the criteria selected as follows:
ARTP (Association for Respiratory Technology and Physiology
)
At least 3 good quality blows must exist within the exam stage
The two largest FVC values must be within 150mL (100mL if FVC<= 1L) of each other
The two largest FEV1 values must be within 150mL (100mL if FVC<= 1L) of each other
The two largest VC values must be within 150mL of each other
ATS/ERS 2019
At least 3 acceptable FEV1 and 3 acceptable FVC must exist within the exam stage
The two largest FVC values must be within 150mL of each other, or for patients aged 6 or
younger, 100mL or 10% of largest FVC, whichever is greater.
The two largest FEV1 values must be within 150mL of each other, or for patients aged 6 or
younger, 100mL or 10% of largest FEV1, whichever is greater.
The two largest VC values must be within 150mL of each other or 10% VC (whichever is
smaller) for patients older than 6 years; and 100mL or 10% of largest FVC, whichever is
smaller (for patients aged 6 or younger).
BTS
At least 3 good quality blows must exist within the exam stage
The two largest FVC values must be within 100mL or 5% (whichever is larger) of each other
The two largest FEV1 values must be within 100mL or 5% (whichever is larger) of each other
The two largest VC values must be within 100mL or 5% (whichever is larger) of each other
