| Abstract | Normal, young, non-smoking men were studied at rest and during submaximal exercise with carboxyhemoglobin (COHb) levels of about 1% and after breathing CO to raise the COHb level to 8 to 9%. Arterial and mixed venous blood was sampled. CO caused an increase in minute volume and breathing frequency during exercise but not at rest. CO caused no changes in cardiac output, heart rate, lactate, lactate/pyruvate ratio, tidal volume, CO2 output or 2,3 DPG during rest or exercise. CO caused a decrease in O2 consumption, in arterial-venous O2 content difference and in venous O2 content and venous Po2 during exercise and in the latter two also at rest. Changes in O2 affinity are still being calculated. |
