The formulas that rely solely on H&H are the Strauss and Duarte formulas, while those which incorporate other parameters include the Hakim and Kaplan formulas.   There is now a large body of evidence that demonstrates these simple formulas can convey prognosis and may be valuable as a prospective measurement to guide therapy.   This review lays out the evidence for using plasma volume calculations in patients with heart failure and the benefits that can be derived from utilizing them in the management of heart failure.}, issn = {2375-1924}, doi = {10.18103/mra.v12i1.5004}, url = {https://esmed.org/MRA/mra/article/view/5004} }
