Does hypercarbia, distinct from acidosis, reduce myocardial contractility and oxygen utilization in isolated perfused rat hearts?
Population
Isolated, spontaneously beating rat heart preparation
Comparison

Hypercarbia may impair contractility beyond acidosis in isolated hearts; hypothesis-generating and should not yet change practice.
Does hypercarbia, distinct from acidosis, reduce myocardial contractility and oxygen utilization in isolated perfused rat hearts?
Hypercarbia, rather than acidosis, is primarily responsible for decreased myocardial contractility and oxygen utilization in the isolated perfused rat heart.
Tang et al. (1991) studied this question.
