Plasma Volume Oscillations during Fluid Therapy in Humans.

Demographic Relationships Univariate testing showed that high wave amplitudes were more likely in females ( p < 0.001), for low body weights (linear regression, r = −0.46, p < 0.001) and when the blood Hb was low at baseline ( r = −0.48, p < 0.001), but they only showed a trend to decrease with age ( p = 0.12).
