This field presents the data regarding the acceptability of spirometry results as a series of none-or-more text flags for researchers unable to work directly with the raw bit-field information in Field 10693
. The text flags are as follows:
START Present if the extrapolated volume at start of test is excessive
EXPFLOW Present if time to peak flow is excessive
END Present if an adequate plateau at the end of the test does not exist
COUGH Present if a cough was detected during the manovoure
BELOW6SEC Set if the test is less than 6 seconds
ACCEPT Present if the test was explicitly acceped by the investigator
REJECT Present if the test was explicitly rejected by the investigator.
Bit-field values of 0 are not translated into strings since they correspond to a blow with no flags set.
