Relationship Between Erythropoiesis and Ventilation in High Altitude Natives

  • Chapter
Response and Adaptation to Hypoxia

Part of the book series: Clinical Physiology Series ((CLINPHY))

Abstract

Erythrocytosis, an increased rate of red blood cell production, is one of the main physiologic adjustments to hypoxia (18). The response is mediated by the glycoprotein hormone, erythropoietin, which is synthesized in the kidney (9). Upon exposure to hypoxia, the erythropoietin concentration increases in the blood of sojourners within about 6 hours (10). Peak concentrations are reached in about 48 hours, and significant elevations can still be measured after 9 days (1). After that, the serum erythropoietin concentration is indistinguishable from sea-level normal. It is not known whether variation in the erythropoietin response can explain the variation in hematocrit observed in sojourners to altitude, but based on a few subjects (14), there seems to be no striking correlation.
