effort tolerance alone;

   + if  respiratory conditions  exist in the absence  of cardiac  disease, the cardiorespiratory functional impairment rating is the rounded average of (i) impairment as measured by effort  tolerance, and (ii) impairment as measured by spirometry;

   + if both cardiac and respiratory conditions co-exist, the cardiorespiratory functional impairment  rating is the greater of (i) the impairment rating as measured by effort tolerance, and (ii) the impairment rating as measured by spirometry.

 In applying these rules, both accepted and non-accepted cardiac and respiratory conditions are to be taken into account.

 Only one rating for effort tolerance is to be given irrespective of the number of conditions that contribute to the relevant impairment.

 Only one rating is to be given for physiological measurements of lung function irrespective of the number of conditions that contribute to the relevant impairment.

 This single "total cardiorespiratory functional impairment" is due to the combined effect of all cardiorespiratory conditions whether accepted or not.

    This nomogram is to be used in accordance with the instructions in Step 5 and the procedural Table 1.5.

    Results from this nomogram are to be rounded to the nearest five points. 2.5 is to be rounded up to 5 and 7.5 is to be rounded up to 10.

     This nomogram corresponds to the formula:

     Impairment
     Rating =

METs Impairment Rating + Impairment Rating of Physiological Measurement
