How much fluid does 5% albumin 'pulls' more than 0.9%Saline ?

Its a common knowledge that albumin increases more intravascular volume than crystalloids. BUT have you wondered by how much ? and where does that volume comes from. Answer may surprise you. We will review the literature on this topic and calculate the fluid shifts that occur with Saline, 5% albumin and 25% albumin.
