title: How often may a Read rebreathing test be repeated?
abstract: The minimum duration of the rest period between repeated Read rebreathing tests required to prevent interference between tests is yet unknown. Four male and four female volunteers performed eight Read rebreathing CO2 response tests in a period of 2.5 h. The test-to-test interval was as short as 10 min. No major differences in slope or intercept were found according to time in either the group as a whole or as male and female groups taken separately. There was a slight but nonsignificant depression in slope for the 3rd to 5th tests. The females responded less to a CO2 challenge than did the males. It is concluded that a test-to-test interval as short as 10 min does not effect the results of the Read rebreathing test.
