Interpretation Tab 20 IQmark Digital Spirometer Operation Manual From this tab, you can select which Reference Equations set to use as the default for Adults and Pediatrics. Not every Spirometry measurement (FVC, FEV1, etc) are calculated by every Reference Equation. The Secondary reference equations can be used to “fill in” missing measurements. For example, if your primary reference equation does not have an equation for FEF25, you can select a secondary reference equation that does to “fill in” your report. Spirometry Settings – Interpretation Tab You can also turn on or off the Auto. Interpretation feature. If the Auto. Interpretation box is selected, you can select the ATS Logic or the NHANES III logic. If you do not wish to have the software automatically interpret the Spirometry tests, clear the Auto. Interpretation box. The Primary Care Practitioner (PCP) Mode overrides Reference Equation and Interpretation selection. It is discussed on the next page.
IQmark Digital Spirometer Operation Manual The third area on this tab, FVC Settings, enables you to define the acceptable length of test required. Reducing this number will affect the length of test acceptability error code. The ATS recommends that the minimum length of test be set to 6 seconds. Primary Care Practitioner (PCP) Mode The PCP Mode automatically selects the NHANES III reference equations and interpretation logic. It also modifies the test acquisition screen, the test review screen and the printed reports. To set the Spirometer into the PCP Mode, the user selects PCP Mode from the pull-down list in the Configuration Profile box and clicks OK. As recommended by the National Lung Health Education Program (NLHEP), this mode simplifies the test procedure, measurements displayed and report options. For the test procedure, it eliminates the inhalation side of the flow volume loop and stops the test at 6 seconds of exhalation. It also eliminates the VC and MVV test selection. For the measurements and reports, it only displays values for FEV1, FEV6 and FEV1/FEV6 and limits the number of digits displayed to two (FEV1 and FEV6 is displayed as X.X Liters and FEV1/FEV6 is displayed as YY %). Any measured values that fall below the Lower Limit of Normal (LLN) will be displayed in red (bold in black and white). After each test maneuver is performed, the software will grade the test session. The quality control grade displayed will be A, B, C, D, or F. A test session must be graded A, B, or C to generate an interpretation and the results of Pre-FVC and Post-FVC tests are only compared if both the Pre and Post sessions are graded A, B, or C. To have the software display “Good Test Session”, you must acquire two acceptable tests that match according to the criteria listed here. QC Grade Criteria A At least two acceptable maneuvers with the largest FEV1 values matching within 100 ml and the largest two FEV6 values matching within 100 ml. B At least two acceptable maneuvers with FEV1 measurements that match between 101 and 150 ml. C At least two acceptable maneuvers with FEV1 measurements that match between 151 and 200 ml. D Only one acceptable maneuver or more than one acceptable maneuver, but the FEV1 values don’t match within 200 ml. F No acceptable maneuvers If the FVC maneuver is less than 6 seconds (because the operator ended the test) but the end of test volume is less than 100 ml during the last 0.5 seconds, then the software will set the FEV6 value equal to the FVC value (if the FVC measurement is valid). 21
