Firor found this a reliable method for providing adequate mixing of the blood and made certain physiologic observations during the procedure. The methods which had been previously used were reviewed3 and attention was called to the fields of investigation in which these procedures had been employed. Recent studies involving the use of cross circulation4 have suggested the need for additional information concerning the accompanying physiologic changes, especially the alterations in plasma and blood volume, the changes in blood pressure and the influence of such changes on the blood volumes, and the rapidity and completeness of mixing of the blood.MATERIAL AND METHOD  SN - 0272-5533 M3 - doi: 10.1001/archsurg.1939.01200180060005 UR - http://dx.doi.org/10.1001/archsurg.1939.01200180060005 ER -
