Supports NO-mediated vasodilation in animal hemodilution; hypothesis-generating and requires human validation before any clinical consideration.
Does high-viscosity plasma increase perivascular nitric oxide concentration in a hamster model of extreme hemodilution?
In extreme hemodilution, high-viscosity plasma increases perivascular nitric oxide concentration, supporting its role in maintaining functional capillary density via NO-mediated vasodilatation.
Tsai et al. (2004) studied this question.
