title: Arterial hypoxia does not affect subchondral pressure and regional blood flow.
abstract: The influence of arterial hypoxia on bone marrow pressure, regional blood flow and oxygen and carbon dioxide tensions was investigated by simultaneous and continuous measurements in the femoral condyles of 8 rabbits. Arterial hypoxia was obtained by hypoventilation. The subchondral gas tensions and regional blood flow were measured by a previously described technique based on mass spectrometry. Arterial hypoxia caused a significant decrease in subchondral oxygen tension and an increase in subchondral carbon dioxide tension. There was no significant change in bone marrow pressure and regional blood flow.
