Blood shift has at least two separate meanings:
- In biology, blood shift may refer to a phenomenon seen when mammals submerge in water. It's part of the mammalian diving reflexes. Blood plasma fills up the thoracic cavity, especially the lungs, and reduces residual volume. Without this adaptation the (human) lungs would shrink and wrap into its walls and have permanent damage at depths below 30 meters. According to Yasemin Dalkılıç she can even feel the plasma fill up her sinuses when diving to extreme depths. [citation needed]
- In medical jargon, in the course of an active infection, the bone marrow may begin to release immature leukocytes into the bloodstream, particularly neutrophil band forms. This is often colloquially referred to by physicians as left shift or blood shift. Blood shift may also refer to a similar phenomenon in severe erythroanemia, when reticulocytes and immature erythrocyte precursors appear in the peripheral circulation. [citation needed]
