Table 1 shall be used to calculate the percentage of disability of the whole body due to permanent partial disability of the respiratory system.
|Symptoms||Forced Spirometry Measurements 1/2 (FEV1 + FVC) (Test three times)||Diffusing Capacity*||Percent Disability of Whole Body|
|When dyspnea occurs, is consistent with the circumstances of activity.||Not less than 85 percent of normal||Not Applicable||0|
|Dyspnea does not occur at rest and seldom occurs during the performance of the usual activities of daily living.||70 to 85 percent of normal||Not Applicable||15|
|Dyspnea does not occur at rest but does occur during the usual activities of daily living.||50 to 70 percent of normal||Usually Not Applicable||30|
|Dyspnea occurs during activities such as climbing one flight of stairs or walking one block on the level.||25 to 50 percent of normal||40 percent or less of normal||60|
|Confined to bed and oxygen dependent.||Less than 25 percent of normal||20 percent or less of normal||85|
* The diffusing capacity studies must be performed when complaints of dyspnea continue unabated in spite of forced spirometric measurement results above the cutoff limits set forth in Table 1.
Asthma which is not medically controllable and which requires at least six hospitalizations in 12 months, 25 percent.
