Partial Pressure Oxygen (mm Hg) ->
Percent Oxygen Saturation
of Hemoglobin

Expert Solution

Step 1 oxygen dissociation curve

oxygen-hemoglobin dissociation curve tells about the oxygen saturation of hemoglobin (binding) with varying range of oxygen pressures( partial pressure)

It can shift either on left side( increase saturation) or right side(decrease saturatin)

It is affected by following--

Left-shifted curve- Caused by:

• High pH (more basic) or low H+ content
• Low temperature
• Low 2,3-BPG
• Fetal Hb (HDF)
• Methemoglobinemia*
• High O2 affinity Hb variants
Low CO2 content
