.01 | pft formula(+) | 0;1 | FREE TEXT | B | This contains the actual formula used for the calculation of PFT predicted values | |
1 | type(+) | 0;2 | FREE TEXT | D | This field is used to indicate which elements of the PFT the formula applies to. For example, a TLC in this field would indicate that this formula is used for Total Lung Capacity predicted values. This field is used as a screen when the formula set is edited. | |
2 | reference | 0;3 | FREE TEXT | C | This field contains the name of the person developing the formula and the year in which it was developed. | |
3 | sex type | 0;4 | SET OF CODES | M:MALE F:FEMALE | E | This field indicates whether the formula applies to male or female patients. |
3.5 | race type | 0;11 | SET OF CODES | B:BLACK O:ORIENTAL | This field is used for doing race corrections on certain PFT elements. It indicates whether the formula for race correction applies to Black or Oriental patients. | |
4 | ci | 0;5 | NUMERIC | This field identifies the confidence interval. It is subtracted from the predicted value to give a 95% confidence interval. Not all elements will have confidence intervals. | ||
