o
Understand the relationship between oxygen and hemoglobin
Oxygen binds to hemoglobin
Oxygen-hemoglobin dissociation curve
Y-axis=% O2 saturation- amount of hemoglobin bound to O2
X-axis= partial pressure of O2
How to read curve. (right to left) the plateau is around PP 104%
mm hg and 98% O2 sat (atrial blood). When gas is exchanged to
the lungs, the venous blood (VB) has a PP is 40% mm Hg and the
O2 stat (hemoglobin saturation) is 75% specifically for the venous
blood (systemic/peripheral venous).
o
As hemoglobin drops off O2, CO2 binds to hemoglobin.
Right before it drops off O2= 98%. After draining= 75%
o
98% O2 Sat of hemoglobin in the atrial blood- 75% O2 Sat
of venous blood= 23% amount of O2 unloaded to tissue
cells
