Appendix C to Part 718 - Blood-Gas Tables

The following tables set forth the values to be applied in determining whether total disability may be established in accordance with § 718.204(b)(2)(ii). The values contained in the tables are indicative of impairment only. They do not establish a degree of disability except as provided in § 718.204(b)(2)(ii) of this subchapter, nor do they establish standards for determining normal alveolar gas exchange values for any particular individual. Tests must not be performed during or soon after an acute respiratory or cardiac illness. A miner who meets the following medical specifications must be found to be totally disabled, in the absence of rebutting evidence, if the values specified in one of the following tables are met:
