... determinant of the change in CO2 excretion rates after catecholamine addition. The most likely explanation is that these data may reflect a minor adrenergic stimulation of CO 2 excretion which was unmasked by these treatments. This apparent stimulation of CO 2 excretion may simply reflect the pHe-depen...
