Plasma expansion may sustain aerobic capacity despite lower hemoglobin; leaves open translation to clinical anemia or heart failure.
Does hemodilution with a plasma expander affect maximum aerobic power and cardiac performance in healthy subjects?
Blood volume size significantly influences cardiac performance, with plasma volume expansion increasing preload and cardiac output via the Frank-Starling mechanism, thereby maintaining maximum aerobic power despite hemodilution.
Kanstrup et al. (1982) studied this question.
