Rinse Back

Hello Gary,

Depending on the machine, the extra-corporeal volume is between 100 ml and 200 ml. I think this loss would be like what you might have if you had a bad cut to a middle-sized artery or vein, but the blood is staunched in a minute or so. If that sort of cut would leave you tired, then perhaps the lack of rinse back caused your fatigue. Otherwise, it might be related to residual effects from your cold and the typical heat in Texas.

I hope you are feeling better now.
