Model predictions of cardiac output for a woman with a normal Hb concentration (13 g/dl) and for anemic women [from Brannon et al. (7)], who had Hb levels of 10.8, 10.7, 9.9, 8.8, and 6.3 g/dl at exercise level 2 (unshaded, patterned bars) and at exercise level 3 (shaded, patterned bars) before CO exposure and in response to the following CO exposures during the preparation of 3 meals: 50 ppm CO for 1 h (meal 1); 0 ppm CO for 2.5 h; 110 ppm CO for 2 h (meal 2); 0 ppm for 2.5 h; and 50 ppm CO for 1 h (meal 3).
