00:01
So in this case let understand this by a diagram.
00:07
So this is x axis and this is y axis.
00:12
This is about the partial pressure of oxygen which is in torr.
00:18
While this is the y or fractional saturation.
00:24
So this is fractional saturation created at the y axis.
00:28
Generally the partial pressure of oxygen to hemoglobin curve is a sigmoidal curve.
00:42
This is the usual graph.
00:44
When this shifted to the right side or there is right shift this means that it has lower affinity which means that there is lower affinity of oxygen to bind to the hemoglobin.
01:05
While when there is left shift this means that there is higher affinity of oxygen to bind to the hemoglobin molecule.
01:22
So in the first case when ph increases from 7 .4 to 7 .8 this means that increase in affinity of oxygen to the hemoglobin.
01:49
And in this scenario the graph shifted towards the left side.
02:05
This means that lower partial pressure of oxygen required to bind to the oxygen...
