Anemic hypoxia REF: Ganong's physiology 22nd edition, chapter 37, Fundamentals of Human Physiology by Lauralee Sherwood page 371 See APPENDIX-16 for "Types of hypoxia" Indirect repeat from June 2008, June 2010 "Approximately 5 g/dL of unoxygenated hemoglobin in the capillaries generates the dark blue color appreciated clinically as cyanosis. For this reason, patients who are anemic maybe hypoxemic without showing any cyanosis"
