anxious,reatless,often confused,may be short of breath
hypovolemic shock,fall in supine bloodpressure,tachycardic with cool,clammy skin
Erythroid marrow response
The capacity of marrow to respond depends on:
the level of erythropoietin stimulation
the presence of a normal complement of erythroid precursors in a normal marrow structure
an aduquate supply of iron
Erythropoietic response to acute hemorrhage

Bohr effect 波尔效应
PH value or H + CO2 concentration and the changes in the differential pressure hemoglobin combined with oxygen ability, the influence of blood pH value reduced or pCO2 rise, make the affinity to reduce Hb O2, in any pO2 next Hb oxygen saturation all lowers oxygen from curve right shift, conversely, pH value rise or pCO2 decrease to increase the affinity of Hb O2, in any pO2 next Hb oxygen saturation increased, oxygen from curve moves left. PH against Hb oxygen acceptor this effect is called Bohr effect.
