Does acetylcholine affect vascular resistance and compliance in isolated blood-perfused dog lungs?
Acetylcholine exhibits concentration-dependent and tone-dependent effects on pulmonary vascular resistance and compliance in canine models, dilating large arteries at low doses and constricting veins at higher doses.
Barman et al. (1989) studied this question.
