The following tables set forth the values to be applied in
determining whether total disability may be established in
accordance with Secs. 718.204(b)(2)(ii) and 718.305(a), (c). The
values contained in the tables are indicative of impairment only.
They do not establish a degree of disability except as provided in
Secs. 718.204(b)(2)(ii) and 718.305(a), (c) of this subchapter, nor
do they establish standards for determining normal alveolar gas
exchange values for any particular individual. Tests shall not be
performed during or soon after an acute respiratory or cardiac
illness. A miner who meets the following medical specifications
shall be found to be totally disabled, in the absence of rebutting
evidence, if the values specified in one of the following tables are
met:
