Professor Harrington of OXYVITA submitted a chapter for publication to a blood substitute specific textbook. As of February 2014, Springer publishing has published this textbook. The text-book is titled Hemoglobin-Based Oxygen Carriers as Red Cell Substitutes and Oxygen Therapeutics.
Furthermore, OxyVita is mentioned more than once through out the textbook. This gives a third party verification of the promise that the OxyVita product line offers!
