Description

Select Protocol

The selected protocol determines the way the spirometer operates when testing a patient. Applicable for FVC testing only. For details, see “Spirometry Protocols” on page 57. • • • • •

None PCP (primary care practitioner) NIOSH OSHA SSD (Social Security & Disability)

Select Adult Predictive Norm

The selected adult norm is the primary source of predictive values for adult patients. For details, see “Norm Profiles” on page 68.

Select Ped. Predictive Norm

The selected pediatric norm is the primary source of predictive values for pediatric patients. For details, see “Norm Profiles” on page 68.

Select Best Effort Formula

A patient’s best effort is a measurement calculated from a set of efforts. To determine the way in which best effort is calculated, choose from these options: • Best Measurement - Defines best effort as the single best effort in a set of efforts (best FVC-pre, best FVCpost, best SVC). This ATS-recommended method uses the effort with the highest sum of FVC + FEV1, or the effort with the highest SVC value. (For details, see the document noted in Reference 6 on page 76.) • Best Composite - Defines best effort as a composite of the highest parameter values across all selected efforts (except FVC and FEV1, which are both selected from the highest sum of FVC + FEV1.)

Description (continued)

Select FVC Reversibility is the percentage difference between pre-test and post-test data for FVC Reversibility Formula testing. This measurement indicates the effect of medication on lung function. Reversibility applies to each parameter separately. To determine the way in which reversibility is calculated, choose from these options: • ((Post-Pre)/Pre)*100 • (Post/Pre)*100 • ((Post-Pre)/Predictive)*100 Select FEV1% Formula

The FEV1% formula determines the calculation method for a test’s (not an effort’s) overall FEV1% value, which affects the automatic interpretation. The variable part of this formula is the denominator. Both the numerator and the denominator represent best effort values. To determine the way in which FEV1% is calculated, choose from these options: • • • •

FVC FIVC FEV6 Max (FVC, FIVC, SVC)

(FEV1% = FEV1/FVC) (FEV1% = FEV1/FIVC) (FEV1% = FEV1/FEV6) (FEV1% = FEV1/FVC or FIVC or SVC, whichever is largest)

Enable Predictive Points

Yes or no. If yes, predictive points display and print. Predictive points may be enabled with or without the predictive curve. For details, see “predictive points” on page 80.

Enable Predictive Curve

Yes or no. If yes, a curve displays and prints along the predictive points. When the curve is enabled, the points are automatically also enabled.

Enable ATS Interp. Results

Yes or no. If yes, ATS interpretative results are included in the test record. For details, see “ATS interpretive results” on page 77.

Enable Composite Norm Values

Yes or no. If yes, any parameters that are not supported in the primary (selected) norm are given predictive values from alternative (composite) norm sources. If set to no, only the primary norm’s values are used, no composite values. On the screen and in reports, any unsupported parameters appear without predictive values. For details, see “About Race Adjustment” on page 70.
