Acceptability of spirometry result (bit field)
START_OF_TEST Set if the extrapolated volume at start of test is excessive = 0x01 TIME_TO_PEF Set if time to peak flow is excessive = 0x02 END_OF_TEST Set if an adequate plateau at the end of the test does not exist = 0x04 COUGHING Set if a cough was detected during the manovoure = 0x08 TEST_DURATION Set if the test is less than 6 seconds = 0x10 USER_ACCEPTED Specifies whether or not the test was explicitly acceped by the investigator = 0x20 USER_REJECTED Specifies whether or not the test was explicitly rejected by the investigator = 0x40
Hence a decimal value of 24 (0x08+0x10) indicates a test of less than 6 seconds during which a cough was detected.
